It is surely frustrating if you’re stuck with a certain software version, since the vulnerabilities that was used by team Pangu for iOS 9 was already patched and as to date, no hacker managed to successfully reveal a new jailbreak.
Community expectations with Pangu team and TaiG are obviously high for them to release their jailbreaks, but then since the last jailbreak only the Italian developer Todesco managed to show one but it’s not available for public and keeping the tool for personal use. At the same time refuses to officially make the jailbreak tool available for public use.
So upgrading to iOS 9.3 is not wise since the testing will soon be offer and the final release will be announced in public afterwards. And according to latest hearsay that we gather, the update will be this coming march so as usual we will be expecting the famous hacking team to release their jailbreak tools.
As for this time, Pangu announced to all of its fans that it is still safe to update the version to iOS 9.2.1 and TaiG is on the way of preparing the iOS 9.3 jailbreak.
