Developers managed to hack the operating system iOS 9.2.1, located at the stage of beta testing. About their success said the expert in information security Luca Todesco, known on the web under the name @qwertyoruiop.
Luca Todesco – known expert in the field of computer security. On the support page of his name appears among the developers that Apple helped to find and close security holes in iOS 9.2.
In Luke’s account Todesco made a reservation that is not going to release a jailbreak for iOS 9.2.1. That does not rule out the possibility that it will give other developers discovered vulnerabilities. Last year Todesco helped hacker group Pangu create a jailbreak for iOS 9.1.
Todesco also is the developer of the jailbreak for iOS 8.4.1. Unfortunately, he did not create common tools for hacking, but was limited to the publication of the source code of the exploit in its repository on Github.
In any case, expect to jailbreak iOS 9.2 / iOS 9.2.1 is only after the upgrade from the beta version. For developers, it makes no sense to do before release, because Apple can close vulnerabilities in the next beta.
