Apple has been working rigorously to patch all the vulnerabilities that Pangu and TaiG were able to exploit in the previous versions. With the release of iOS 9.2 or iOS 9.2.1 jailbreak early, chances are the company might come up with a solution to patch those with the release of iOS 9.3 next.
Although no public jailbreak release for iOS has arrived since the last Pangu 9 jailbreak for iOS 9.0-9.0.2, iOS hacker qwertyoruiop has demonstrated that it is possible to jailbreak untethered iOS 9.2, 9.2.1, and 9.3 beta.
The hacker demonstrated a video of the untethered jailbreak of iPhone 6 running iOS 9.2, where he launched Cydia to verify his iOS version, started Mobile Terminal to run his command, and even played with WinterBoard theme.
