On Apple devices running iOS and iOS-based[a] 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 unavailable 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.[1]

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).[8] Users install these programs for purposes including personalization and customization of the interface using tweaks developed by developers and designers,[8] adding desired features such as access to the root file system and fixing annoyances,[9] and making development work on the device easier by providing access to the file system and command-line tools.[10][11] 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.[12]
Cybercriminals may jailbreak an iPhone to install malware or target jailbroken iPhones on which malware can be installed more easily. The Italian cybersecurity company Hacking Team, which sells hacking software to law enforcement agencies, advised police to jailbreak iPhones to allow tracking software to be installed on them.[20][21]
On iOS devices, the installation of consumer software is generally restricted to installation through the App Store. Jailbreaking, therefore, allows the installation of pirated applications.[22] It has been suggested that a major motivation for Apple to prevent jailbreaking is to protect the income of its App Store, including third-party developers and allow the buildup of a sustainable market for third-party software.[23] However, the installation of pirated applications is also possible without jailbreaking, taking advantage of enterprise certificates to facilitate the distribution of modified or pirated releases of popular applications.[24]
A package manager or package-management system is a collection of software tools that automates the process of installing, upgrading, configuring, and removing computer programs. For jailbreaks, this is essential for the installation of third-party content. There are a few package managers specifically for jailbroken iOS devices, of which the most popular are Cydia, Sileo, Zebra and Installer 5.
In March 2021, jailbreak developer GeoSn0w[25] released a tweak called iSecureOS which can alert the users of security issues found on their devices. The application works akin to antivirus software, in that it scans the files on the user device and check them against a database of known malware or unsafe repos.
When a jailbroken device is booting, it loads Apple's own boot software initially. The device is then exploited and the kernel is patched every time it is turned on. An untethered jailbreak is a jailbreak that does not require any assistance when it reboots up. The kernel will be patched without the help of a computer or an application.[33] These jailbreaks are uncommon and take a significant amount of reverse engineering to create. For this reason, untethered jailbreaks have become much less popular, and Fugu14[34] is currently the only jailbreak that supports recent iOS versions.
A tethered jailbreak is the opposite of an untethered jailbreak, in the sense that a computer is required to boot the device. Without a computer running the jailbreaking software, the iOS device will not be able to boot at all. While using a tethered jailbreak, the user will still be able to restart/kill the device's SpringBoard process without needing to reboot. Many early jailbreaks were offered initially as tethered jailbreaks.
A few days after the original iPhone became available in July 2007, developers released the first jailbreaking tool for it,[35] and soon a jailbreak-only game app became available.[36] In October 2007, JailbreakMe 1.0 (also called "AppSnapp") allowed people to jailbreak iPhone OS 1.1.1 on both the iPhone and iPod Touch,[37][38] and it included Installer.app as a way to get software for the jailbroken device.
The iPhone Dev Team, which is not affiliated with Apple, has released a series of free desktop-based jailbreaking tools. In July 2008 it released a version of PwnageTool to jailbreak the then new iPhone 3G on iPhone OS 2.0 as well as the iPod Touch,[40][41] newly including Cydia as the primary third-party installer for jailbroken software.[42] PwnageTool continues to be updated for untethered jailbreaks of newer iOS versions.[43][44]
An iOS 6.X untethered jailbreak tool called "evasi0n" was released for Linux, OS X, and Windows on February 4, 2013.[67] Due to the high volume of interest in downloading the jailbreak utility, the site initially gave anticipating users download errors. When Apple upgraded its software to iOS 6.1.3 it permanently patched out the evasi0n jailbreak.[68]
International treaties have influenced the development of laws affecting jailbreaking. The 1996 World Intellectual Property Organization (WIPO) Copyright Treaty requires nations party to the treaties to enact laws against DRM circumvention. The American implementation is the Digital Millennium Copyright Act (DMCA), which includes a process for establishing exemptions for non-copyright-infringing purposes such as jailbreaking. The 2001 European Copyright Directive implemented the treaty in Europe, requiring member states of the European Union to implement legal protections for technological protection measures. The Copyright Directive includes exceptions to allow breaking those measures for non-copyright-infringing purposes, such as jailbreaking to run alternative software,[123] but member states vary on the implementation of the directive.
Apple's support article concerning jailbreaking claims that they "may deny service for an iPhone, iPad, or iPod Touch that has installed any unauthorized software."[127] Therefore, anyone who is jailbroken, warranty or not, may or may not get support from Apple considering assistance with jailbreaking.
In 2007, Tim Wu, a professor at Columbia Law School, argued that jailbreaking "Apple's superphone is legal, ethical, and just plain fun."[145] Wu cited an explicit exemption issued by the Library of Congress in 2006 for personal carrier unlocking, which notes that locks "are used by wireless carriers to limit the ability of subscribers to switch to other carriers, a business decision that has nothing whatsoever to do with the interests protected by copyright" and thus do not implicate the DMCA.[146] Wu did not claim that this exemption applies to those who help others unlock a device or "traffic" in software to do so.[145]
On October 28, 2012, the US Copyright Office released a new exemption ruling. The jailbreaking of smartphones continued to be legal "where circumvention is accomplished for the sole purpose of enabling interoperability of [lawfully obtained software] applications with computer programs on the telephone handset." However, the U.S. Copyright office refused to extend this exemption to tablets, such as iPads, arguing that the term "tablets" is broad and ill-defined, and an exemption to this class of devices could have unintended side effects.[149][150][151] The Copyright Office also renewed the 2010 exemption for unofficially unlocking phones to use them on unapproved carriers, but restricted this exemption to phones purchased before January 26, 2013.[150] In 2015, these exemptions were extended to include other devices, including tablets.[152]
BigBoss (previously TheBigBoss.org) is a software repository and blog for jailbreaking. It publishes news on the topic and allows developers to host tweaks and other extensions.[153] It was one of the first repositories to exist for the Cydia package manager, launched in April 2008 by Sleepers Repository. It comes preinstalled with all copies of Cydia.[154]
In recent years, due to the technical complexity and often rarity of legitimate jailbreaking software (especially untethered jailbreaks) there has been an increase in websites offering fake iOS jailbreaks. These websites often ask for payment or make heavy use of advertising, but have no actual jailbreak to offer. Others install a fake, lookalike version of the Cydia package manager.[173] In some cases, users have been asked to download free-to-play apps or fill out surveys to complete a (non-existent) jailbreak.
