You Cannot Downgrade to iOS 9.2

If you decide that the iOS 9.2.1 problems and performance are unbearable you have no choice but to ride it out.

Apple stopped signing on the iPhone 6 iOS 9.2 update which means you can no longer take advantage of a loophole and downgrade to it if the going gets tough on iOS 9.2.1.
