On Apple devices running iOS and iOS-based operating systems, jailbreaking is the use of a privilege escalation exploit to remove software restrictions imposed by the manufacturer. Typically it is done through a series of kernel patches. A jailbroken device permits root access within the operating system and provides the right to install software not available through the App Store. Different devices and versions are exploited with a variety of tools. Apple views jailbreaking as a violation of the end-user license agreement, and strongly cautions device owners not to try to achieve root access through the exploitation of vulnerabilities.While sometimes compared to rooting an Android device, jailbreaking is the bypassing of several types of Apple prohibitions for the end-user. Since it includes modifying the operating system (enforced by a "locked bootloader"), installing non-officially approved (not available on the App Store) applications via sideloading, and granting the user elevated administration-level privileges (rooting), the concepts of iOS jailbreaking are therefore technically different from Android device rooting.
