Pangu developers have released a Chinese version of a jailbreak tool for iOS 9.2 to 9.3.3. The English version should be online soon. The tool is only available for the Windows platform, but Pangu usually releases an OS X version later as well.
The tool only works with 64-bit devices, i.e. all iPhones since the 5s, iPod Touch 6G, and iPads since the iPad Mini 2 and the iPad Air. It is unknown whether there will be an official 32-bit version.
The app works slightly differently than previous versions. With this version, the iOS device is back in ‘unjailbroken’ state after a reboot. To get a device back into a jailbroken state after a reboot, you need to run the PP app that is installed during the jailbreak process.
The 59 megabyte program makes use of certain vulnerabilities in iOS. Which the Chinese developers used for this is unknown. Because Apple closes leaks in every update, jailbreaks usually no longer work after an update of the operating system.
A jailbreak allows users to install apps and tweaks that are otherwise not possible. The Pangu team previously released jailbreaks for iOS 7.1, iOS 8 and iOS 9. At the beginning of this year, an Italian, who once participated in a Pangu jailbreak, announced that he had made a jailbreak for iOS 9.2.1, but that he wouldn’t release it.
