The iPod Touch (trademarked, marketed and stylized as iPod touch) is a portable media player, personal digital assistant, and Wi-Fi mobile platform designed and marketed by Apple Inc. The product was launched on September 5, 2007, at an event called The Beat Goes On.[4] The iPod Touch adds the multi-touch graphical user interface to the iPod line. It is the first iPod with wireless access to the iTunes Store, and also has access to Apple's App Store, enabling content to be purchased and downloaded directly on the device. Apple Inc. has sold 20 million iPod Touch units as of September 2009.[5]

The 2nd generation iPod Touch, featuring external volume controls, a built-in speaker, a contoured back, built-in Nike+, Bluetooth support, and the ability to connect a microphone, was unveiled on September 9, 2008, at the "Let's Rock" keynote presentation.

The 3rd generation iPod Touch with the new iPhone OS 3.1 was announced and subsequently released on September 9, 2009.[6] It is available with 32 or 64 GB of flash memory. Apple also continued offering the 2nd generation 8 GB version.[7] The new 3rd generation iPod Touch[8] includes faster hardware (the same microprocessors, graphics engine, and RAM as the iPhone 3GS), a slightly lower battery life, voice control, light sensor, and bundled earphones with a remote and microphone.

Hardware

The iPod Touch has a slim rectangular shape with rounded edges, with a glass touchscreen display covering most of the top surface and a physical home button off the touchscreen. The display functions similarly to the multi-touch trackpad as implemented in Apple's current line of laptop computers. The touch and gesture features of the iPod Touch are based on technology originally developed by FingerWorks.[9] On February 5, 2008, a 32 GB version was added in addition to the 8 and 16 GB versions. On September 9, 2009, a 64 GB version was added and the 16 GB version was removed from the line-up.

Software

The home screen has a list of icons for the available applications. All iPod Touch models include such applications as Music, Videos, and Photos (collectively duplicating the standard functions of the iPod Classic), iTunes (providing access to the iTunes Music Store), Safari, YouTube, Calendar, Contacts, Clock, Calculator, and Settings. Later models added Mail (accessing POP/IMAP/SMTP e-mail), Maps, Stocks, Notes, and Weather, which could also be added to the earlier models with the purchase of a software upgrade. The user can add direct links to Web sites, called "Web Clips", to the home screen. All iPod Touch models are equipped with Wi-Fi 802.11b/g.

On July 11, 2008, the iPhone 2.0 Software Update was released for purchase for the iPod Touch. The update allowed 1st generation iPod Touch devices access to the App Store to download third-party applications, in addition to a host of minor bug fixes. On June 17, 2009, the iPhone 3.0 Software Update was released for purchase for the iPod Touch. The update allowed the devices to use new apps, and unlocked the Bluetooth functionality of the 2nd generation iPod Touch, enabling A2DP and P2P apps, as well as file transfer to other (non Apple) devices such as bluetooth-enabled mobile phones or jailbroken iPods using software such as iBlueNova.

Comparisons to the iPhone and model comparisons

Further information: [[:iPhone OS]] and [[:iPhone OS version history]]

The iPod Touch and the iPhone, a smartphone by Apple Inc., share the same hardware platform and run the same iPhone OS operating system. The iPod Touch lacks some of the iPhone's features and associated apps, such as access to cellular networks, or a built-in speaker and camera (and microphone on older models). As a result, the iPod Touch is slimmer and lighter than the iPhone. Multimedia, which is available as a single "iPod" app on the iPhone, is split into music and movies on the iPod Touch. Steve Jobs once referred to the iPod Touch as "training wheels for the iPhone".[10]

The 2nd generation iPod Touch has an external volume switch and a built-in speaker like the iPhone. The 2nd generation also comes with the chrome frame seen on the iPhone 3G, making the two almost identical when viewed from the front. However, there are some notable differences, as there is no speaker above the screen, no silent/ringer switch, the back is metal, and the sleep/wake button is on the other side. The 2nd generation also supports audio input when a headphone or earphone with microphone capabilities is plugged into the audio output (headphone) jack. The iPod Touch 2.0 Software Update supports WPA2 Enterprise with 802.1X authentication.[11] The iPhone OS 3.0 update unlocked Bluetooth capability on the 2nd generation iPod Touch, as the included Wi-Fi chip (Broadcom BCM4325) has Bluetooth support.[12][13]

The 2nd generation iPod Touch is said to have a yellower cast/tint to the display, as compared to the iPhone or the original iPod Touch.[14] The applications processor inside the 2nd generation iPod Touch runs slightly faster than the processor inside the iPhone 3G, but slower than the iPhone 3GS.[15][16] The first generation iPod Touch works with all "Made for iPod" peripherals, but certain changes that Apple made to the 2nd generation iPod Touch prevent some existing peripherals from recharging the updated player.[17] The Google Street View feature added on iPhone firmware version 2.2 is absent from the same version of firmware released on the iPod Touch [18] but is found in the 3.0 update.

Apple has received criticism for its differential treatment of iPhone and iPod Touch owners. Such criticism is primarily targeted towards Apple charging iPod Touch owners for major software updates of the iPhone OS that iPhone owners can obtain at no charge as well as excluding certain features from the iPod Touch software that are included in the iPhone.[19][20] Apple has been reported as saying that they can add features for free to the iPhone because the revenue from it is accounted for on a subscription basis under accounting rules, rather than as a one time payment.[21]

Requirements

As supplied new, the iPod Touch needs a connection to a computer for initial configuration,[24] for syncing media and installing system software updates. Officially, Apple requires iTunes to be installed on either a Mac OS X or Windows operating system based computer for configuring the iPod Touch. On either operating system, the iPod Touch must be connected through a USB port.[25] The 2nd generation (and onward) iPod Touch will not connect nor charge using older iPod Firewire cables.

Starting with the 2nd generation iPod Touch only can be charged from the 5V pin of the dock connector, while most previous iPod models and the original iPod Touch could also be charged from the 12V pin for firewire power,[23] resulting in the newer iPod Touch not charging in vehicles equipped with an firewire-based iPod connection. Most aftermarket manufacturers[who?] of such equipment however are producing new cables and/or adapters, that essentially just kick down the voltage from 12 to 5.[citation needed]

The first time the iPod Touch is turned on, a "connect cable to iTunes" graphic will be displayed continuously until the iPod Touch is connected to a computer running iTunes.[26]

To use the iPod Touch for buying products at the iTunes Music Store via Wi-Fi, an iTunes Music Store account must be created and the account details then entered into the iPod.[citation needed]

Apple states that the following is required for the iPod Touch:[27]

  • A computer running either:
    • Mac OS X 10.4.10 or later
    • Microsoft Windows XP with SP2 or later, or Microsoft Windows Vista (32 or 64-bit versions)
  • iTunes 8.2 for iPhone OS 3.0.x or later, iTunes 8.0 for iPhone OS 2.1.x, iTunes 7.6 for iPhone OS 2.0.x or earlier
  • Available USB 2.0 port

Third-party applications

File:App Store 2.2.png
App Store on iPod Touch
Earphones with an external microphone and controller are compatible with the 2nd generation iPod Touch, and are shipped with the 3rd generation iPod Touch.

The only official way to obtain third-party applications for the iPod Touch is Apple's App Store, which is a branch of iTunes Store. The App Store application, available in all versions of the iPhone OS from iPhone OS 2.0 onwards, allows users to browse and download applications from a single online repository (hosted by Apple) with the iTunes Store. To develop such software, a software development kit (SDK) was officially announced on March 6, 2008, at an Apple Town Hall meeting.[28] The iPhone SDK allows developers to make applications for the iPhone and iPod Touch after paying a fee to join the development team. The developer can then set the price for the applications they develop and will receive 70% of money earned. The developer can also opt to release the application for free and will not pay any additional costs.

Shortly after the iPod Touch was released, hackers were able to "jailbreak" the device through a TIFF exploit. The application installed by this exploit enabled the user to download a selection of unofficial third-party programs. Jailbreaking the iPod Touch was, in fact, the only way to get third-party programs when running 1.1.x OSes. These third-party programs could use additional functionality not supported by Apple (such as enabling multitasking or applying themes to the home screen. All officially released versions of the iPhone OS through 3.1.2 can be jailbroken,[29][30] but version 3.1 could not at the time it was released.[31] Servicing an iPod Touch after jailbreaking or other modifications made by unofficial means is not covered by Apple's warranty (however, the jailbreaking process is easily undone by performing a restore through iTunes).[32]
