Jailbreak tools vary from jailbreak to jailbreak. Some tools consist of tiny utilities that must be executed from a Mac or Windows machine, while other jailbreak methods can be executed right on device without needing to connect to a computer.
Pangu today released a jailbreak tool that allows users to jailbreak iOS 9.3.3 on eligible 64-bit iPhones and iPads. As of now, the tool is only available in Chinese and is Windows-only. An English version should be arriving shortly.
Out of seemingly nowhere, the Pangu hacking team has released an update to its jailbreak tool for devices running iOS 9.1. The tool, which is available for both Mac and Windows, allows users to jailbreak the iPad, iPhone and iPod touch. More interestingly, the same team is promising to release a jailbreak for the 4th generation Apple TV next week. expand full story
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.
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). Users install these programs for purposes including personalization and customization of the interface by tweaks developed by developers and designers, adding desired features such as access to the root file system and fixing annoyances, and making development work on the device easier by providing access to the file system and command-line tools. 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.
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.
Upon jailbreaking the device, a lot of the built-in security is lost due to the vast amount of kernel patches that go into building the tool. Security structures like Apple Mobile File Integrity, Sandbox, Read-Only Root File system, and trusted apps get disabled or otherwise tampered with, to achieve the goals of the jailbreaking tool. This, in turn, creates potential security issues for the jailbreak user.
A few days after the original iPhone became available in July 2007, developers released the first jailbreaking tool for it, and soon a jailbreak-only game app became available. 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, 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, newly including Cydia as the primary third-party installer for jailbroken software. PwnageTool continues to be updated for untethered jailbreaks of newer iOS versions.
After Apple released iPhone OS 3.0 in June 2009, the Dev Team published redsn0w as a simple jailbreaking tool for Mac and Windows, and also updated PwnageTool primarily intended for expert users making custom firmware, and only for Mac. It continues to maintain redsn0w for jailbreaking most versions of iOS 4 and iOS 5 on most devices.
George Hotz developed the first iPhone unlock. In 2009, he released a jailbreaking tool for the iPhone 3GS on iPhone OS 3.0 called purplera1n, and blackra1n for iPhone OS version 3.1.2 on the 3rd generation iPod Touch and other devices.
Nicholas Allegra (better known as "comex") released a program called Spirit in May 2010. Spirit jailbreaks devices including iPhones running iPhone OS 3.1.2, 3.1.3, and iPad running iPhone OS 3.2. In August 2010, comex released JailbreakMe 2.0, the first web-based tool to jailbreak the iPhone 4 (on iOS 4.0.1).In July 2011, he released JailbreakMe 3.0, a web-based tool for jailbreaking all devices on certain versions of iOS 4.3, including the iPad 2 for the first time (on iOS 4.3.3). It used a flaw in PDF file rendering in mobile Safari.
Chronic Dev Team initially released Greenpois0n in October 2010, a desktop-based tool for untethered jailbreaking iOS 4.1 and later iOS 4.2.1 on most devices including the Apple TV, as well as iOS 4.2.6 on CDMA (Verizon) iPhones.
The iPhone Dev Team, Chronic Dev Team, and pod2g collaborated to release Absinthe in January 2012, a desktop-based tool to jailbreak the iPhone 4S for the first time and the iPad 2 for the second time, on iOS 5.0.1 for both devices and also iOS 5.0 for iPhone 4S. In May 2012 it released Absinthe 2.0, which can jailbreak iOS 5.1.1 untethered on all iPhone, iPad, and iPod Touch models that support iOS 5.1.1, including jailbreaking the third-generation iPad for the first time.
An iOS 6.X untethered jailbreak tool called "evasi0n" was released for Linux, OS X, and Windows on February 4, 2013. 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.
On October 14, 2015, Pangu Team released Pangu9, their untethered jailbreak tool for iOS 9.0 through 9.0.2. On March 11, 2016, Pangu Team updated their tool to support iOS 9.1 for 64-bit devices.
On December 21, 2016, a beta semi-untethered jailbreak tool for iOS 10.1 known as yalu+mach_portal was released for select 64-bit iOS devices. The jailbreak made use of Ian Beer's, of Google Project Zero, mach_portal exploit. This version is extremely unstable and was only meant for developers. On January 26, 2017, with help from Marco Grassi, a more stable version for iOS 10.2 was released, eventually supporting all 64-bit iOS devices except for the iPhone 7 and 7 Plus, which is only supported by the older, more unstable version for 10.1.1. This jailbreak made use of Ian Beer's, of Project Zero, extra_recipe exploit. Both jailbreaks are installed through a computer application known as Cydia Impactor, which allows signing of apps not in the App Store. Todesco said that the newer version would be eventually updated to support the iPhone 7 and 7 Plus up to iOS 10.1.1, however, he left the jailbreaking scene on March 28, abandoning both jailbreaks before it was released.
On June 6, 2018, Abraham Masri released an update to Houdini, the first semi-jailbreak. The tool has been updated to beta 3 revision 1, adding the compatibility with iOS 11 up to 11.3.1.
The main law that affects the legality of iOS jailbreaking in the United States is the 1998 Digital Millennium Copyright Act (DMCA), which says "no person shall circumvent a technological measure that effectively controls access to a work protected under" the DMCA, since this may apply to jailbreaking. Every three years, the law allows the public to propose exemptions for legitimate reasons for circumvention, which last three years if approved. In 2010 and 2012, the U.S. Copyright Office approved exemptions that allowed smartphone users to jailbreak their devices legally, and in 2015 the Copyright Office approved an expanded exemption that also covers other all-purpose mobile computing devices, such as tablets. It is still possible Apple may employ technical countermeasures to prevent jailbreaking or prevent jailbroken phones from functioning. It is unclear whether it is legal to traffic in the tools used to make jailbreaking easy.
The latest Pangu jailbreak tool allows the user to jailbreak iOS devices on the demand. The user can easily jailbreak the iOS devices by running the click-to-jailbreak app, and also easily remove the jailbreak by rebooting the iOS devices. In other words, the user has full control to enable or disable the jailbreak functionality.
Although iOS 15 jailbreak tools have not come to the scene by this time, mature jailbreaks for iOS 14 - iOS 14.6（surely including iOS 14.2, 14.3, 14.4, 14.5) do exist, supporting you in getting your Apple devices out of restrictions. The next two parts will successively introduce how to jailbreak iOS 14-14.6 with and without computer using jailbreak utilities.
It's a hassle-free Jailbreak. Before you start to jailbreak your device running on iOS 9.3.3, you should backup your iOS device to iTunes or iCloud first and download the following files. Cydia Impactor is a GUI based tool used to sign the .iPA file of Pangu jailbreak to install and execute it on iOS devices. 2b1af7f3a8
