For those of you who are jailbroken on iOS 9.0-9.0.2, it is important to note that just like iOS 9.1, the just released iOS 9.2 is not jailbreakable either. If you are on iOS 9.0 to 9.0.2 and care about jailbreaking, DO NOT update to iOS 9.2 yet. If you are on iOS 9.1 though, it is probably best to update iOS 9.2.
