Apple users waiting for an iOS 9.3.1 jailbreak update must be aware that existing tools, which claim to do the job, are all fake. The only claimed success we know at this point is the one built by Luca Todesco, but of course, he is not sharing. The Italian hacker is reportedly able to jailbreak an iPhone running iOS 9.3.
For instance an iOS 9.3.x jailbreak tool which goes by the name "3K Jailbreak" is nothing more but hoax, Redmond Pie notes. On top of being fake, it can also bring dangerous malwares and viruses, so users are advised to avoid it. Do not be confused, as it is not created by the 3K Assistant team.
This only means that to date, there is no fully-functional jailbreak tool available for iOS 9.3.1. Because Chinese jailbreak teams Pangu and TaiG do not usually provide pre-release updates, users on the lookout for available tools fall for scams and their common result in the form of malwares.
It has been reported that iOS 9.3 and 9.3.1 are using roughly the same level of security, which means exploits pushed in the earlier software can be carried out in the later build. Apple itself has written, "iOS 9.3.1 includes the security content of iOS 9.3."
It must also be noted that Apple has stopped signing some firmwares, Neurogadget reports. These include iOS 9.2.1, which disables downgrading from iOS 9.3 or 9.3.1, and iOS 9.3, which disables downgrading from a later software, such as when a jailbreak tool becomes available.
For those who may not know, Apple released the fourth iOS 9.3.2 beta earlier this month, MacRumors says, for developers and public beta testers. The update comes a week after release of the third beta. It can be downloaded over-the-air (OTA) or through the Developer site.
Note: Jailbreak tools are available for earlier firmwares. While the process is legal, it does not come without risks, so it is important to have complete understanding before initiating tools. If you change your mind, it is removable through restoration via iTunes.
