Windknown, one of the core Pangu Jailbreak Team members, recently posted a technical article explaining the security and vulnerability fixes found in iOS 9.2 and iOS 9.2.1.
In his post, Windknown went on to explain several technical details that discussed specific kernel exploits that could be used to jailbreak the operating system. Those of you who have an understanding of programming, specifically the code found in the iOS platform, might be interested in checking the details out further (translated post via Google Translate). The part that was most interesting though was what was mentioned by the hacker towards the end of his article. A rough translation of what was mentioned stated that the vulnerability found can be triggered in the iOS sandbox, so it can attack the kernel right from the app to obtain the kernel code execution permission. He continued by recommending that users upgrade to the latest version as soon as possible and avoid installing apps from unknown sources.
The conversation this issue starts is whether users should update to iOS 9.2.1 due to security vulnerabilities or if they should stick with iOS 9.2 in the hopes of a public jailbreak release. Another issue is that no one has confirmed information on whether iOS 9.2.1 can be jailbroken by the Pangu team or if the team even plans on releasing a jailbreak for this version of iOS. Both of these issues continue to remain unknown but we do have further insight based on the recommendation to an extent.
The suggestion to upgrade to iOS 9.2.1 is likely an opinion that is geared towards the security aspect as it may be risky to sideload apps. There might even be a possibility that apps from the Apple Store could contain malicious codes, such as the incident that occurred with Xcode previously. Issues like these could potentially put your device at a big risk so taking precaution where possible is usually advised.
The iOS hacker, Luca Todesco (@qwertyoruip), who recently revealed a video of an untethered jailbreak for iOS 9.2.1, iOS 9.2 and iOS 9.3 beta, also recently tweeted to windknown stating the following:
By the way I agree with @windknown 100% re. p0 bugs. Update to 9.2.1 if you don’t care about jailbreak. Stick on 9.2 if you do.

It seems that the signals are mixed and it should be noted that neitehr party mentioned anything of releasing a jailbreak. What do you plan on doing? Are you going to stick with your current jailbroken device? Update to iOS 9.2.1 or stay on iOS 9.2? Share your thoughts below!
