iPhone 5 iOS 9.2 Update: 7 Things to Know Right Now

iOS 9.2 Jailbreak

And finally, it's worth noting that developers have yet to release a working jailbreak for iOS 9.1 or iOS 9.2 beta. 

A jailbreak for both iOS 9.1 and iOS 9.2 beta has been found but it's not clear if the jailbreak will be released to the general public. Developers haven't confirmed one way or the other and they probably won't ahead of a potential release.

If you're looking to jailbreak iOS 9, you need to be on iOS 9.0.2, iOS 9.0.1 or iOS 9.0. For now.
