If you don't like iOS 9.2's features or performance, you're going to have to seek out manual fixes because you can no longer downgrade to iOS 9.1.
Apple's closed up the loophole and it's no longer signing on iOS 9.1. This means that once you decide to bump up to iOS 9.2 you're going to be stuck there until Apple releases its next update. Something to keep in mind if you're coming from an older update like iOS 8 or iOS 7. There's no going back once you move to iOS 9. |
