iOS 9.2.1 Jailbreak
If you're jailbroken, don't update to the iOS 9.2.1 update because you'll lose your jailbreak.
Developers have teased a number of new iOS 9 jailbreak releases but none of them have been released to the public. A new iOS 9 jailbreak could be close but it's not clear if it will arrive for iOS 9.2, iOS 9.2.1 or some other update.
For now, all you can do is stay put if you're jailbroken and cross your fingers if you've already moved to something older than iOS 9.0.2.
