iOS Jailbreaking• iOS jailbreaking, or simply jailbreaking, is the process of removing the limitations imposed by Apple on devices running the iOS operating system through use of custom kernels.• Jailbreaking allows users to gain root access to the operating system, allowing iOS users to download additional applications, extensions, and themes that are unavailable through the official Apple App Store.
• A tethered jailbreak requires that the device be connected to a computer each time it needs to be booted; an untethered jailbreak allows the device to be powered without computer assistance.• Under the Digital Millennium Copyright Act, jailbreaking iPhones is legal in the United States, although Apple has announced that the practice "can violate the warranty".
Reasons for Jailbreaking• One of the main reasons for jailbreaking is to expand the feature set limited by Apple and its App Store.• Since software programs available through Cydia are not required to adhere to App Store guidelines, many of them are not typical self-contained apps but instead are extensions and customizations for iOS and other apps.
