The iPhone is an internet-connected multimedia smartphone designed and marketed by Apple Inc. with a flush multi-touch screen and a minimal hardware interface. The device does not have a physical keyboard, so a virtual keyboard is rendered on the touch screen instead. The iPhone functions as a camera phone (including text messaging and visual voicemail), a portable media player (equivalent to an iPod), and Internet client (with email, web browsing, and local Wi-Fi connectivity). The first generation phone hardware was quad-band GSM with EDGE; the second generation also adds UMTS with HSDPA.[9]

Apple announced the iPhone on January 9, 2007.[10] The announcement was preceded by rumors and speculation that circulated for several months.[11] The iPhone was initially introduced in the United States on June 29, 2007 and has since been introduced worldwide. It was named Time magazine's "Invention of the Year" in 2007.[12] On July 11, 2008, the iPhone 3G was released and supported faster 3G data speeds and Assisted GPS.[9]

Development of iPhone began with Apple CEO Steve Jobs' direction that Apple engineers investigate touchscreens.[13] Apple created the device during a secretive and unprecedented collaboration with AT&T Mobility—Cingular Wireless at the time—at a development cost of US$150 million over thirty months. Apple rejected the "design by committee" approach that had yielded the Motorola ROKR E1, a largely unsuccessful collaboration with Motorola. Instead, Cingular gave Apple the liberty to develop the iPhone's hardware and software in-house. Numerous codenames and even fake prototypes were devised to keep the project secret.[14][15]

Jobs unveiled iPhone to the public on January 9, 2007 in a keynote address. Apple was required to file for operating permits with the FCC, but such filings are available to the public, so the announcement came several months before the iPhone received approval. The iPhone went on sale in the United States on June 29, 2007. Apple closed its stores at 2:00 pm local time to prepare for the 6:00 pm iPhone launch, while hundreds of customers lined up at stores nationwide.[1] On launch weekend, Apple sold 270,000 iPhones in the first thirty hours.[16] The original iPhone was made available in the UK, France, and Germany in November 2007, and Ireland and Austria in spring of 2008.

On July 11, 2008, Apple released the iPhone 3G in twenty-two countries, including the original six.[17] Forty-eight more are expected to follow in the months afterwards.[18] Apple sold 1 million iPhone 3Gs in its first 3 days on sale,[19] enough to overload Apple's United States iTunes servers.[20]

On October 21, 2008 Apple announced sales of 6.89 million iPhone 3Gs in the fourth quarter of 2008, totaling 13 million iPhones to date.[21] iPhone slaes from that quarter surpassed RIM's BlackBerry sales of 5.2 million units. By revenue, Apple is the third largest mobile phone manufacturer, after Nokia and Samsung.[22] Within Apple's fiscal fourth quarter, up to September 30, 2008, the iPhone represented 39 percent (US$4.6 billion) of the company's total quarterly revenues, although some of this income is deferred.[23]

  • Assisted GPS, with preference to location based on Wi-Fi or cell towers
  • Digital SAR Rating: 1.38 W/kg

Screen and input

The 9 cm (3.5 in) liquid crystal display (320×480 px at 6.3 px/mm, 160 ppi) HVGA touchscreen with scratch-resistant glass[25] is specifically created for use with a finger, or multiple fingers for multi-touch sensing. Because the screen is a capacitive touchscreen, bare skin is required. Most gloves or a stylus prevent the necessary electrical conductivity. The screen is also capable of rendering up to 262,144 colors.[28][29][30][31]

The display responds to three sensors. A proximity sensor shuts off the display and touchscreen when the iPhone is brought near the face during a call. This is done to save battery power and to prevent inadvertent inputs from the user's face and ears. An ambient light sensor adjusts the display brightness which in turn saves battery power. A 3-axis accelerometer senses the orientation of the phone and changes the screen accordingly.[32] Photo browsing, web browsing, and music playing support both upright and left or right widescreen orientations.[33] Later, a software update allowed the first generation iPhone to use cell towers and Wi-Fi networks for location finding despite lacking a hardware GPS. The iPhone 3G supplements those methods with A-GPS.

The iPhone has three physical switches on the sides: wake/sleep, volume up/down, and ringer on/off. These are made of plastic on the original iPhone and metal on the iPhone 3G. A single "home" hardware button below the display brings up the main menu. The touch screen furnishes the remainder of the user interface.

The back of the original iPhone was made of brushed metal with a black plastic accent. The iPhone 3G features a full plastic back to increase GSM signal strength.[34] The plastic is black for the 8 GB model, but the 16 GB version is also available in white.

Audio

The iPhone's headphones are similar to those of most current smartphones, incorporating a microphone. A multipurpose button in the microphone can be used to play or pause music, skip tracks, and answer or end phone calls without touching the iPhone; newer versions also incorporate volume controls. A small number of third-party headsets specifically designed for the iPhone also include a microphone and control button.[35]

The 3.5 mm TRS connector for the headphones is located on the top left corner of the device. The headphone socket on the original iPhone is recessed into the casing, making it incompatible without the use of an adapter.[36][37] The iPhone 3G has a flush mounted headphone socket.

Wireless earpieces that use Bluetooth technology to communicate with the iPhone are sold separately. It does not support stereo audio.

The loudspeaker is used both for handsfree operations and media playback.

Composite or component video at up to 576i and stereo audio can be output from the dock connector using an adapter sold by Apple.[38]

Unlike many similar phones, the iPhone requires third party software to support voice recording.

Battery

The iPhone features an internal rechargeable battery. It is not user-replaceable, similar to the batteries of existing iPods, but dissimilar to those of most existing cellular phones.[36][39] If the battery malfunctions or dies prematurely, the phone can be returned to Apple and replaced for free while still under warranty.[40] The warranty lasts one year from purchase and is extended to two years with AppleCare. The cost of having Apple provide a new battery and replace it when the iPhone is out of warranty is slightly less than half the cost of a new 8 GB iPhone.[41]

Since July 2007 third party battery replacement kits have been available[42] at a much lower price than Apple's own battery replacement program. These kits often include a small screwdriver and an instruction leaflet, but as with many newer iPod models the battery in the original iPhone has been soldered in. Therefore a soldering iron is required to install the new battery. The iPhone 3G uses a different battery fitted with a connector, although replacing the battery oneself still voids the warranty.[43]

The original iPhone's battery was stated to be capable of providing up to seven hours of video, six hours of web browsing, eight hours of talk time, 24 hours of music or up to 250 hours on standby.[25] Apple's site says that the battery life "is designed to retain up to 80% of its original capacity after 400 full charge and discharge cycles",[44] which is comparable to the iPod batteries.

The iPhone 3G's battery is stated to be capable of providing up to seven hours of video, six hours of web browsing on Wi-Fi or five on 3G, ten hours of 2G talk time, or five on 3G, 24 hours of music, or 300 hours of standby.[7]

The Foundation for Taxpayer and Consumer Rights, a consumer advocate group, has sent a complaint to Apple and AT&T over the fee that consumers have to pay to have the battery replaced.[45] Though the battery replacement service and its pricing was not made known to buyers until the day the product was launched,[45][46] a similar service had been well established for the iPods by Apple and various third party service providers.

SIM card

The SIM card is located in a slot at the top of the device. It can be ejected with a paperclip or a tool included with the iPhone 3G.[47] In most countries, the iPhone is usually sold with a SIM lock, which prevents SIM cards from being used on different mobile networks.

Storage

The iPhone was initially released with two options for internal storage size: 4 GB or 8 GB. On September 5, 2007, Apple discontinued the 4 GB models.[48] On February 5, 2008, Apple added a 16 GB model.[49] All data is stored on an internal flash drive; the iPhone does not contain any memory card slots for expanded storage.

Included items

Both the iPhone and the iPhone 3G include (or included) written documentation, stereo earbuds with microphone, a dock connector to USB cable, and a cloth for cleaning the screen. The original iPhone also included plastic dock to hold the iPhone upright; it is not compatible with the iPhone 3G, for which a slightly different dock is sold separately. The iPhone 3G includes a tool to eject the SIM card; the original model required a paperclip for this purpose. Both versions include a USB power adpater, although iPhone 3Gs sold in North America, Japan, Columbia, Ecuador, or Peru[50][51] include a more compact version than those bundled with other iPhone 3Gs, or the original model.

Software

Main article: iPhone OS
See also: iPhone OS version history
File:IPhonehomescreen.PNG
The default Home screen of the iPhone shows applications provided by Apple. User can download additional applications from the App store, create Web Clips, and rearrange the icons as they please.

iPhone OS is the operating system running on the iPhone (both original and 3G models) and the iPod Touch. It is based on a variant of the same basic Mach kernel that is found in Mac OS X. iPhone OS includes the software component "Core Animation" from Mac OS X v10.5 which, together with the PowerVR MBX 3D hardware, is responsible for the interface's smooth animations. The operating system takes up less than half a GB of the device's total 8 GB or 16 GB storage.[52] It is capable of supporting bundled and future applications from Apple, as well as from third-party developers. Software applications cannot be copied from Mac OS X but must be written and compiled specifically for the iPhone.

Like the iPod, the iPhone is managed with iTunes version 7.3 or later, which is compatible with Mac OS X version 10.4.10 or later, and 32-bit or 64-bit Windows XP or Vista.[53] The release of iTunes 7.6 expanded this support to include 64-bit versions of XP and Vista,[54] and a workaround has been discovered for previous 64-bit Windows operating systems.[55] Apple provides free updates to the iPhone's operating system through iTunes, in a similar fashion to the way that iPods are updated.[52] Security patches, as well as new and improved features, are released in this fashion.[56] For example, iPhone 3G users initially experienced dropped calls until an update was issued.[57][58]

Interface

The interface is based around the home screen, a graphical list of available applications. iPhone apps normally run one at a time, although most functionality is still available when making a call or listening to music. The home screen can be accessed at any time by a hardware button, closing the open application in the process.[59] By default, the Home screen contains the following icons: Text (SMS messaging), Calendar, Photos, Camera, YouTube, Stocks, Maps (Google Maps), Weather, Clock, Calculator, Notes, Settings, iTunes (store), and App Store. Docked at the base of the screen; Phone, Mail, Safari (Internet), and iPod (music) delineate the iPhone's main purposes.[60] On January 15, 2008, Apple released software update 1.1.3, allowing users to create "Web Clips", home screen icons that resemble apps that open a user-defined page in Safari. After the update, iPhone users can rearrange and place icons on up to nine other adjacent home screens, accessed by a horizontal swipe.[61] Users can also add and delete icons from the dock, which is the same on every home screen. Each home screen holds up to sixteen icons, and the dock holds up to four icons.

Almost all input is given through the touch screen, which understands complex gestures using multi-touch. The iPhone's interaction techniques enable the user to move the content up or down by a touch-drag motion of the finger. For example, zooming in and out of web pages and photos is done by placing two fingers on the screen and spreading them farther apart or bringing them closer together, an gesture known as "pinching". Scrolling through a long list or menu is achieved by sliding a finger over the display from bottom to top, or vice versa to go back. In either case, the list moves as if it is pasted on the outer surface of a wheel, slowly decelerating as if affected by friction. In this way, the interface simulates the physics of a real 3D object. Other visual effect include horizontally sliding sub-selection, the vertically sliding keyboard and bookmarks menu, and widgets that turn around to allow settings to be configured on the other side. Menu bars are found at the top and bottom of the screen when necessary. Their options vary by program, but always follow a consistent style motif. In menu hierarchies, a "back" button in the top-left corner of the screen displays the parent folder.

Phone

The iPhone allows audio conferencing, call holding, call merging, caller ID, and integration with other cellular network features and iPhone functions. It does not support Voice dialing and video calling.

The iPhone includes a visual voicemail (in some countries) feature allowing users to view a list of current voicemail messages on-screen without having to call into their voicemail. Unlike most other systems, messages can be listened to and deleted in a non-chronological order by choosing any message from an on-screen list. AT&T, O2, T-Mobile Germany, and Orange modified their voicemail infrastructure to accommodate this new feature designed by Apple.[citation needed]

A music ringtone feature was introduced in the United States on September 5, 2007. Users can create custom ringtones from songs purchased from the iTunes Store for a small additional fee. The ringtones can be 3 to 30 seconds long from any part of a song, can fade in and out, pause from half a second to five seconds when looped, or loop continuously. All customizing can be done in iTunes, and the synced ringtones can also be used for alarms. Custom ringtones can also be created using Apple's GarageBand software 4.1.1 or later (available only on Mac OS X)[62] and third-party tools.[63] Custom ringtones are not supported in some countries.

Multimedia

The layout of the music library is similar to that of an iPod or current Symbian S60 phones. The iPhone can sort its media library by songs, artists, albums, videos, playlists, genres, composers, podcasts, audiobooks, and compilations. Options are always presented alphabetically, except in playlists, which retain their order from iTunes. The iPhone uses a large font that allows users to touch their selection. Users can rotate their device horizontally to access Cover Flow. Like on iTunes, it shows the different album covers in a scroll-through photo library. Scrolling is achieved by swiping a finger across the screen.

The iPhone supports gapless playback.[64]

Like the fifth generation iPods introduced in 2005, the iPhone can play video, allowing users to watch TV shows and films. Unlike other image-related content, video on the iPhone plays only in the landscape orientation, when the phone is turned sideways. Double tapping switches between wide-screen and full-screen video playback.

The iPhone allows users to purchase and download songs from the iTunes Store directly to their iPhone over Wi-Fi with the iTunes Wi-Fi Music Store, and as of Macworld San Francisco 2009, over the cellular data network.[65]

Internet connectivity

Internet access is available when the iPhone is connected to a local area Wi-Fi or a wide area GSM or EDGE network, both second-generation (2G) wireless data standards. The iPhone 3G also supports third-generation UMTS and HSDPA 3.6,[66] but not HSDPA 7.2 or HSUPA networks. AT&T introduced 3G in July 2004,[67] but as late as 2007 Steve Jobs felt that it was still not widespread enough, and the chipsets not energy efficient enough, to be included in the iPhone.[29][68] The iPhone 3G has a maximum download rate of 1.4 Mbp/s.[69] Support for 802.1X, an authentication system commonly used by university and corporate Wi-Fi networks, was added in the 2.0 version update.[70]

By default, the iPhone will ask to join newly discovered Wi-Fi networks and prompt for the password when required. Alternatively, it can join closed Wi-Fi networks manually.[71] The iPhone will automatically choose the strongest network, connecting to Wi-Fi instead of EDGE when it is available.[72] Similarly, the iPhone 3G prefers 3G to 2G, and Wi-Fi to either.[73] Users can disable all wireless connections by activating Airplane Mode.

Safari is the iPhone's native web browser, and it displays pages similar to its Mac OS X counterpart. Web pages may be viewed in portrait or landscape mode and supports automatic zooming by pinching together or spreading apart fingertips on the screen, or by double-tapping text or images.[74][75] The iPhone supports neither Flash[76] nor Java.[77] Consequently, the UK's Advertising Standards Authority banned an advertisement claiming the iPhone could access "all parts of the Internet" on grounds of false advertising.[78] The iPhone supports SVG, CSS, HTML Canvas, and Bonjour.[79][80]

The maps application can access Google Maps in map, satellite, or hybrid form. It can also generate directions between two locations, while providing optional real-time traffic information. Support for walking directions, public transit, and street view was added in the version 2.2 software update.[57] During the iPhone's announcement, Jobs demonstrated this feature by searching for nearby Starbucks locations and then placing a prank call to one with a single tap.[13][81] Apple also developed a separate application to view YouTube videos on the iPhone, which streams videos over Wi-Fi, 2G, or 3G after encoding them using the open H.264 codec. Simple weather and stock quotes also tap in to the Internet.

iPhone users can and do access the internet frequently, and in a variety of places. According to Google, the iPhone generates 50 times more search requests than any other mobile handset.[82] According to Deutsche Telekom CEO René Obermann, "The average Internet usage for an iPhone customer is more than 100 megabytes. This is 30 times the use for our average contract-based consumer customers."[83]

Text input

File:IPhone keyboard unblured.jpg
Virtual keyboard on the original iPhone's touchscreen.

For text input, the iPhone implements a virtual keyboard on the touchscreen. It has automatic spell checking and correction, predictive word capabilities, and a dynamic dictionary that learns new words. The keyboard can predict what word the user is typing and complete it, and correct for the accidental pressing of keys adjacent to the presumed desired key. The keys are somewhat larger and spaced farther apart when in landscape mode, which is supported by only a limited number of applications. Holding a finger over a section of text brings up a magnifying glass, allowing users to place the cursor in the middle of existing text. The iPhone does not support cut, copy, or pasting text.[84] The virtual keyboard can accommodate 21 languages, including character recognition for Chinese.[85] A lack of focus on text-messaging is widely considered a chief weakness of the iPhone, although a large number of users evidently have no issue using the device for this purpose.[86]

E-mail

The iPhone also features an e-mail program that supports HTML e-mail, which enables the user to embed photos in an e-mail message. PDF, Word, Excel, and Powerpoint attachments to mail messages can be viewed on the phone.[87] Apple's MobileMe platform offers push email, which emulates the functionality of the popular BlackBerry email solution, for an annual subscription. Yahoo! offers a free push-email service for the iPhone. IMAP (although not Push-IMAP) and POP3 mail standards are also supported, including Microsoft Exchange[88] and Kerio MailServer.[89] In the first versions of the iPhone firmware, this was accomplished by opening up IMAP on the Exchange server. Apple has also licensed Microsoft ActiveSync and now supports the platform (including push email) with the release of iPhone 2.0 firmware.[90][91] The iPhone will sync e-mail account settings over from Apple's own Mail application, Microsoft Outlook, and Microsoft Entourage, or it can be manually configured on the device itself. With the correct settings, the e-mail program can access almost any IMAP or POP3 account.[92]

Camera and photos

The photo display application

The iPhone features a built in 2.0 megapixel camera located on the back for still digital photos. It has no optical zoom, flash or autofocus, and does not support video recording. Version 2.0 of iPhone OS introduced the capability to embed location data in the pictures, producing geocoded photographs.

The iPhone includes software that allows the user to upload, view, and e-mail photos. The user zooms in and out of photos by sliding two fingers further apart or closer together, much like Safari. The Camera application also lets users view the camera roll, the pictures that have been taken with the iPhone's camera. Those pictures are also available in the Photos application, along with any transferred from iPhoto or Aperture on a Mac, or Photoshop in Windows.

Third party applications

See also: iPhone SDK and App Store

At WWDC 2007 on June 11, 2007 Apple announced that the iPhone would support third-party "web applications" written in AJAX that share the look and feel of the iPhone interface.[93] On October 17, 2007, Steve Jobs, in an open letter posted to Apple's "Hot News" weblog, announced that a software development kit (SDK) would be made available to third-party developers in February 2008. The iPhone SDK was officially announced on March 6, 2008, at the Apple Town Hall facility.[94] It allows developers to develop native applications for the iPhone and iPod Touch, as well as test them in an "iPhone simulator". However, loading an application onto the devices is only possible after paying a Apple Developer Connection membership fee. Developers are free to set any price for their applications to be distributed through the App Store, of which they will receive a 70 percent share.[95] Developers can also opt to release the application for free and will not pay any costs to release or distribute the application beyond the membership fee. The SDK was made available immediately, while the launch of applications had to wait until the firmware update which was released on July 11, 2008.[91] The update was free for iPhone users, but not for iPod Touch owners, whose devices can run iPhone applications only after paying a small fee.[96]

Once a developer has submitted an application to the App Store, Apple holds firm control over its distribution. For example, Apple can halt the distribution of applications it deems inappropriate as has happened with a US$1000 program that has as sole purpose to demonstrate the wealth of its user.[97]

Apple has been criticized for banning third party applications that enable a functionality that Apple doesn't want the iPhone to have. In 2008, Apple banned Podcaster, which allowed iPhone users to download podcasts directly to the iPhone, bypassing iTunes. Apple has since released a software update that grants this capability.[57] NetShare, another rejected app, would have enabled users to tether iPhones to laptop (or desktop) computers and thereby use the iPhone as an Internet modem.[98]

Many third-party Safari "applications" and unsigned native applications are also available.[99] The ability to install native applications onto the iPhone outside of the App Store will not be supported by Apple. Such native applications could be broken by any software update, but Apple has stated it will not design software updates specifically to break native applications other than applications that perform SIM unlocking.[100] As of September 15, 2008, iPhone software version 2.1 is still "exploitable" by the same method that enabled unsigned applications in software versions as early as version 1.1.3, indicating that Apple is making good on their promise not to intentionally cripple unofficial development.

Others

The built-in Bluetooth 2.x+EDR supports wireless earpieces, which requires the HSP profile, but notably does not support stereo audio (requires A2DP), laptop tethering (requires DUN and SPP), or the OBEX file transfer protocol (requires FTP, GOEP, and OPP). The lack of these profiles prevent iPhone users from exchanging multimedia files with other bluetooth-enabled cell phones, including pictures, music and videos.

Text messages are presented chronologically in a mailbox format similar to Mail, which places all text from recipients together with replies. Text messages are displayed in speech bubbles (similar to iChat) under each recipient's name. The iPhone currently has built-in support for e-mail message forwarding, drafts, and direct internal camera-to-e-mail picture sending. However, it does not yet have capabilities for delivery reports, MMS, or copy/cut/paste.[101][84] Support for multi-recipient SMS was added in the 1.1.3 software update.[57]

Accessibility

The iPhone can enlarge text to make it more accessible for vision-impaired users,[102] and can accommodate hearing-impaired users with closed captioning and external TTY devices.[103] Nevertheless, Apple states that "[e]ffective use of the iPhone requires a minimal level of visual acuity, motor skills, and an ability to operate a few mechanical buttons. Use of iPhone by someone who relies solely on audible and tactile input is not recommended."[104] The iPhone 3G has not been rated under the United States Federal Communication Commission guidelines for hearing aid compatibility at either level M3 or T3.[104]

Patents, copyrights, and trademarks

Apple has filed more than 200 patents related to the technology behind the iPhone.[105][106]

LG Electronics claimed the iPhone's design was copied from the LG Prada. Woo-Young Kwak, head of LG Mobile Handset R&D Center, said at a press conference, “We consider that Apple copied Prada phone after the design was unveiled when it was presented in the iF Design Award and won the prize in September 2006.”[107]

On September 3, 1993, Infogear filed for the U.S. trademark "I PHONE"[108] and on March 20, 1996 applied for the trademark "IPhone".[109] "I Phone" was registered in March 1998,[108] and "IPhone" was registered in 1999.[109] Since then, the I PHONE mark had been abandoned.[108] Infogear's trademarks cover "communications terminals comprising computer hardware and software providing integrated telephone, data communications and personal computer functions" (1993 filing),[108] and "computer hardware and software for providing integrated telephone communication with computerized global information networks" (1996 filing).[110] Infogear released a telephone with an integrated web browser under the name iPhone in 1998.[111] In 2000, Infogear won an infringement claim against the owners of the iphones.com domain name.[112] In June 2000, Cisco Systems acquired Infogear, including the iPhone trademark.[113] On December 18, 2006 they released a range of re-branded Voice over IP (VoIP) sets under the name iPhone.[114]

In October 2002, Apple applied for the "iPhone" trademark in the United Kingdom, Australia, Singapore, and the European Union. A Canadian application followed in October 2004 and a New Zealand application in September 2006. As of October 2006 only the Singapore and Australian applications had been granted. In September 2006, a company called Ocean Telecom Services applied for an "iPhone" trademark in the United States, United Kingdom and Hong Kong, following a filing in Trinidad and Tobago.[115] As the Ocean Telecom trademark applications use exactly the same wording as Apple's New Zealand application, it is assumed that Ocean Telecom is applying on behalf of Apple.[116] The Canadian application was opposed in August 2005 by a Canadian company called Comwave who themselves applied for the trademark three months later. Comwave have been selling VoIP devices called iPhone since 2004.[113]

Shortly after Steve Jobs' January 9, 2007 announcement that Apple would be selling a product called iPhone in June 2007, Cisco issued a statement that it had been negotiating trademark licensing with Apple and expected Apple to agree to the final documents that had been submitted the night before.[117] On January 10, 2007 Cisco announced it had filed a lawsuit against Apple over the infringement of the trademark iPhone, seeking an injunction in federal court to prohibit Apple from using the name.[118] More recently, Cisco claimed that the trademark lawsuit was a "minor skirmish" that was not about money, but about interoperability.[119]

On February 2, 2007, Apple and Cisco announced that they had agreed to temporarily suspend litigation while they hold settlement talks,[120] and subsequently announced on February 20, 2007 that they had reached an agreement. Both companies will be allowed to use the "iPhone" name[121] in exchange for "exploring interoperability" between their security, consumer, and business communications products.[122]

Restrictions

SIM Lock removal

Unlocked iPhone firmware version 2.0 using GrameenPhone Network in Bangladesh, India.

While initially iPhones were only sold on the AT&T network with a SIM lock in place, various hackers have found methods to "unlock" the phone; more recently some carriers have started to sell unlocked iPhones.[123] More than a quarter of iPhones sold in the United States were not registered with AT&T. Apple speculates that they were likely shipped overseas and unlocked.[124] AT&T has stated that the "iPhone cannot be unlocked, even if you are out of contract".[125]

On November 21, 2007, T-Mobile in Germany announced it would sell the phone unlocked and without a T-Mobile contract, caused by a preliminary injunction against T-Mobile put in place by their competitor, Vodafone.[126] On December 4, 2007, a German court decided to grant T-Mobile exclusive rights to sell the iPhone with SIM lock, overturning the temporary injunction.[127] In addition, T-Mobile will voluntarily offer to unlock customers' iPhone after the termination of the contract.[128]

On carriers where removal of the iPhone's SIM lock is allowed, the carrier can submit a request to Apple which will then remove the carrier locking on the next restore of the iPhone through iTunes. Note that in certain countries, where unlocked phones are required to be available by law, the iPhone is sold without a contract and without a SIM lock; on average, such units carry prices of US$700+ for the 8 GB model. Examples include Hong Kong, Italy, New Zealand, and Russia.[129] In Australia, all three carriers (Optus, Telstra, and Vodafone) will also provide an unlock after requesting it from the carrier.[129]

Activation

The iPhone normally prevents access to its media player and web features unless it has also been activated as a phone with an authorized carrier. On July 3, 2007, Jon Lech Johansen reported on his blog that he had successfully bypassed this requirement and unlocked the iPhone's other features with a combination of custom software and modification of the iTunes binary. He published the software and offsets for others to use.[130]

Unlike the original, the 3G iPhone must be activated in the store in most countries.[131] This need for in-store activation, as well as the huge number of first-generation iPhone and iPod Touch users upgrading to iPhone OS 2.0, caused a worldwide overload of Apple's servers on July 11, 2008, the day on which both the iPhone 3G and iPhone OS 2.0 updates were released. After the update, devices were required to connect to Apple's servers to authenticate the update, causing many devices to be temporarily unusable.[132]

Users on the O2 network in the United Kingdom, however, can buy the phone online and activate it via iTunes as with the previous model.[133] iPhones purchased in Australia as a pre-paid kit likewise do not require in-store activation, but require activation online at the Optus website and iTunes.[134] Buyers can also activate iPhones via iTunes on Spain's Movistar network. Shops usually offer activation for the buyer's convenience.

Third party applications

The iPhone's operating system is designed to only run software that has an Apple-approved cryptographic signature. This restriction can be overcome by "jailbreaking" the phone,[135] which involves replacing the iPhone's firmware with a slightly modified version that does not enforce the signature check. Doing so may be a circumvention of Apple's technical protection measures,[136] which in the United States would be legal under special provisions of the Digital Millennium Copyright Act that allows for circumvention for the purpose of connecting a wireless telephone to a wireless telephone communication network.[137]
