iOS jailbreaking – AppleTV 4 Jailbreak (appletv4jailbreak.com)
On Apple devices running iOS and iPadOS-based operating systems, jailbreaking is a privilege escalation executed 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 opportunity 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 from attempting to achieve root access through exploitation of vulnerabilities.[1]
While sometimes compared to rooting an Android device, jailbreaking is the bypass 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 are different.
Motivation
One of the reasons for jailbreaking is to expand the feature set limited by Apple and its App Store.[2] Apple checks apps for compliance with its iOS Developer Program License Agreement before accepting them for distribution in the App Store. However, their reasons for banning apps are not limited to safety and security and may be regarded as arbitrary and capricious.[3] In one case, Apple mistakenly banned an app by a Pulitzer-Winning cartoonist because it violated its developer license agreement, which specifically bans apps that “contain content that ridicules public figures.”[4] To access banned apps,[5] users rely on jailbreaking to circumvent Apple’s censorship of content and features. Jailbreaking permits the downloading of programs not approved by Apple,[6] such as user interface customization and tweaks.
Device customization
Since software programs available through APT and or Installer.app (legacy) are not required to adhere to App Store guidelines, many of them are not typical self-contained apps but instead are extensions and customization options for iOS and its features and other apps (commonly called tweaks).[7] Users install these programs for purposes including personalization and customization of the interface by tweaks developed by developers and designers,[7] adding desired features such as access to the root file system and fixing annoyances,[8] and making development work on the device easier by providing access to the filesystem and command-line tools.[9][10] Many Chinese iOS device owners also jailbreak their phones to install third-party Chinese character input systems because they are easier to use than Apple’s.[11]
In some cases, jailbreak features are adopted by Apple and used as inspiration for features that are incorporated into iOS and iPadOS.
