Research How to Downgrade to iOS 9.2 or iOS 9.1

You'll always be able to downgrade from iOS 9.2.1 beta to a public version of iOS 9 and it would be smart to familiarize with the process before you jump to the software. It will make your life a little bit easier. We put together an iOS 9 downgrade guide that will show you how to drop back down. 

As a reminder, you'll only be able to drop back down to iOS 9.1 (for a limited time) and iOS 9.2 from iOS 9.2.1 beta. You can't go back to anything else so you'll want to make sure the jump to iOS 9.2.1 beta is the right move for you.
