Jailbreaking is a process that allows iPhone and iPod Touch users to run any code on their devices, as opposed to only that code authorized by Apple. Once jailbroken, iPhone users are able to download many applications previously unavailable through the App Store via unofficial installers such as Cydia; Icy; and Installer, as well as illegal pirated apps. A jailbroken iPhone or iPod Touch is still able to use and update apps downloaded and purchased from Apple's official App Store.

Jailbreaking is distinct from SIM unlocking, which, once completed, means that the mobile phone will accept any SIM without restriction on, for example, the country or network operator of origin. Jailbreaking, according to Apple, voids Apple's warranty on the device, although this is quickly remedied by restoring the device in iTunes.

Cydia founder Jay Freeman estimates that 8.5% of all iPods and iPhones are jailbroken.[1]

History

The first jailbreaking method was released on July 10, 2007, which initially was meant to provide a way to use custom ringtones.[2] On August 6, 2007 the first third-party game was released for the iPhone and iPod Touch.[3]

On October 10, 2007, about 3 months after the original iPhone was released, another method to jailbreak the iPhone was discovered.[4] Apple and hackers then engaged in a cat-and-mouse game to patch up security holes and to exploit them. Hackers eventually released a tool to permanently jailbreak iPhone OS 1.0.

Upon the release of iPhone OS 2.0, a hacker group called the iPhone Dev Team released a jailbreaking application named PwnageTool that used a graphical user interface.[5]

In January 2009, the iPhone Dev Team commenced work on jailbreaking the iPod Touch 2G.[6] redsn0w lite was the code name for a tethered iPod Touch 2G jailbreak, and in April, redsn0w 0.1 was released.[7]

On March 10, 2009, the untethered jailbreak was released for the iPod Touch 2G utilizing an exploit found by the Chronic Dev Team, and developed with the help of iPhone Dev Team member planetbeing. It was released as a rough patch, and was not implemented into a GUI until next month, when planetbeing made redsn0w based on QuickPwn sources.

On March 17, 2009, Apple announced the release of iPhone OS 3.0.[8] Three months later, the iPhone Dev Team released PwnageTool 3.0 and redsn0w 0.7.2, which allowed users of the original iPhone, iPhone 3G, and iPod Touch running the OS 3.0 to be jailbroken on both Macs and PCs.[9]

On September 9, 2009, Apple released iPhone OS 3.1, again disabling the ability to jailbreak the device. Once again the dev team released a jailbreak for all devices (except for the iPod Touch 3rd Generation), called Pwnage Tool 3.1-3.[10]

On October 11, 2009, George Hotz, known under alias geohot, released the tool blackra1n, which allows the jailbreaking of all iPhones (Up to 3GS) and iPod touch (Up to 3G) devices running iPhone OS 3.1.2 (although the iPod touch 3rd generation and iPhone 3GS are tethered; they must be plugged into a computer every time it boots).

On November 2, 2009 Hotz released a newer version of blackra1n, RC3, an update that was able to jailbreak the iPhone 3G and iPhone 3GS along with a tethered jailbreak on the iPod Touch 3G 8GB model. This included the most recently-manufactured devices that featured an updated boot ROM in which Apple had closed the 24kpwn loophole exploited by previous jailbreaks. Hotz also released blacksn0w an unlocking application for the iPhone which was capable of unlocking the newest baseband version, 5.11.07.

Greenpois0n, a jailbreak program not unlike PwnageTool is currently in development, but is being held back so that Apple cannot patch the exploit used before the 4th generation iPhone. Greenpois0n uses a type of jailbreak said to be different in kind from any earlier program, which would thus be effective for some time before Apple manages to patch up the exploit.

1.0 - 1.0.2 iPhone Yes (none)

3.1 - 3.1.2 iPhone, iPhone 3G, iPhone 3GS, iPod Touch 1st Generation, and iPod Touch 2nd Generation (non-MC model) Yes (none)
3.1 - 3.1.2 iPhone 3GS (with iBoot-359.3.2) and iPod Touch 3rd generation Yes Tethered (Device must be re-jailbroken every time it is restarted.)
3.1.3 iPhone, iPhone 3G, iPhone 3GS, iPod Touch 1st Generation, iPod Touch 2nd Generation (non-MC model), iPhone 3GS (with iBoot-359.3.2) and iPod Touch 3rd generation Yes Device must be jailbroken on 3.1.2 before upgrading using custom 3.1.3 firmware. Note: Apple no longer signs any firmware besides 3.1.3. Only signed firmware can be installed on an iPhone 3GS, which means once it has been upgraded to 3.1.3, it cannot be downgraded to 3.1.2 and hence, cannot be jailbroken. The only exception is if the device's SHSH file has been previously backed up while it was jailbroken. If an iPhone 3GS user upgrades to 3.1.3 without having their SHSH file backed up, it is impossible to jailbreak the device.
3.2 iPad No Not publicly available.

Viruses/worms

The first iPhone worm appeared in early November 2009, created by 21-year-old Australian technical college student Ashley Towns of Wollongong. He told Australian media that he created the worm to raise awareness of security issues.[24] "When people jailbreak their phone, it allows them to install a service on their phone called SSH... Generally you should always change your password after setting up on the iPhone as all iPhones use the same password by default. This worm exploits people's laziness to change their password", adding that "it basically only changes their wallpaper to Rick Astley. Although the worm is harmless, the source code, initially released to the public, can become the basis for more malicious code. This virus was called iKee. As the source code was released for the virus, many new viruses have appeared although these ones are more harmful.

On 22 November 2009, F-Secure reported on a new malicious worm compromising bank transactions from jailbroken phones in the Netherlands.[25][26]

The legality of jailbreaking an iPod or iPhone remains unclear, particularly in the context of the Digital Millennium Copyright Act. As part of the 2009 DMCA rulemaking, the Electronic Frontier Foundation asked the US Copyright Office to recognize an exemption to the DMCA to permit jailbreaking in order to allow iPhone owners to use their phones with applications that are not available from Apple's store.[27] In response to this, Apple filed comments opposing this exemption and indicating that they do consider jailbreaking to be a violation of copyright (and by implication prosecutable under the DMCA). A ruling on this proposed exemption has not yet been made, but a decision is expected sometime later in 2010.

iPhone Dev Team

Main article: iPhone Dev Team

The iPhone Dev Team is a group of hackers in the iPhone OS community who have developed many hacking (jailbreaking) and unlocking applications for Apple Inc.'s iPhone and iPod Touch devices. These applications provide owners with the ability to sidestep the limitations placed on devices by the manufacturer, allowing for activities such as deep customization and SIM unlocking. Although they are not always the first to create jailbreak tools for new versions of the iPhone OS and new models of iPhone and iPod, their releases are widely considered[by whom?] to be the most reliable and bug-free - and often also boast the most customization options.
