What is iOS Jailbreaking

iOS jailbreaking of ipad-iphone

Jailbreaking is a process that allows iPadiPhone, iPod Touch, and recently Apple TV users to gain root access to the command line of the iOS operating system, thereby removing usage and access limitations imposed by Apple. Once jailbroken, iPhone users are able to download extensions and themes that are unavailable through the App Store (via installers such as Cydia) and perform other tasks that are not possible on store-bought devices, including installing non-Apple operating systems such as Linux. A jailbroken iPad, iPhone oriPod Touch running iOS can still use the App Store and iTunes and other normal functions, such as making telephone calls.

Jailbreaking is different 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 the owners choice. Jailbreaking, according to Apple, can void Apple’s warranty on the device.Under the DMCA of 2010, jailbreaking is perfectly legal in the United States, although Apple may claim it to void your warranty. It is also legal in many other countries including the EU. The jailbreaking process can be quickly and easily reversed by restoring the device in iTunes.

Cydia creator Jay Freeman estimates that over 10% of all iPhones are jailbroken

The first jailbreaking method was released on July 10, 2007, when an American teenager wanted to keep on T-Mobile when Apple locked their iPhones to the US Carrier AT&T, and a month later the first third-party game was released for the iPhone and iPod Touch.Three months after the initial jailbreak, another method was discovered, which led to a cat and mouse game between Apple and hackers to patch and exploit security holes.

All software used is untethered unless otherwise stated. An untethered jailbreak means the user is able to reboot their iDevice without the need to connect to a computer and re-running the jailbreak tool to power up the iDevice.
