10 Things to Know About the iOS 9.2 Beta

You Can Downgrade to iOS 9.0.2 or iOS 9.1

If you're already on iOS 9.0.2 or iOS 9.1, you can try the iOS 9.2 beta without any penalty. That's because you can currently downgrade to either one of those from the iOS 9.2 beta. 

Apple's closed the downgrade path to iOS 8 and anything older than iOS 9.0.2 so if you're coming from one of those you'll need to be sure that moving to the iOS 9.2 beta is something you want. 

Apple will, at some point, close up the iOS 9.0.2 downgrade but you'll always have a way to drop back down to iOS 9.1 or whatever the current update is.
