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 are different. While sometimes compared to rooting an Android device, jailbreaking is the bypass of several types of Apple prohibitions for the end user. Apple views jailbreaking as a violation of the end-user license agreement, and strongly cautions device owners from attempting to achieve root access through exploitation of vulnerabilities. Different devices and versions are exploited with a variety of tools. A jailbroken device permits root access within the operating system and provides the opportunity to install software not available through the iOS App Store.

On Apple devices running iOS operating systems, jailbreaking is a privilege escalation executed to remove software restrictions imposed by the manufacturer.
