5 Reasons Not to Install iOS 9.2 Beta & 4 Reasons to Do It

Don't Install iOS 9.2 Beta If You're Jailbroken

Developers haven't released an iOS 9.2 jailbreak or an iOS 9.1 jailbreak so you won't want to move to either of those updates. 

Apple could plug up the iOS 9.0.2 downgrade at any time so you'll probably want to avoid any move to iOS 9.1 or iOS 9.2.
