A Way to Downgrade to iOS 8.4
Expect there to be a way to downgrade back down to iOS 8.4 if iOS 8.4.1 isn't to your liking. Just don't expect it to last forever.
When the iOS 8.4.1 update is released, expect Apple to continue to sign for the iOS 8.4 update. This leaves a loophole for a downgrade back to iOS 8.4. We expect the downgrade to be available for one to two weeks before Apple stops signing off on iOS 8.4. Once Apple stops signing, you won't be able to get to any software but iOS 8.4.
So, it's important to get familiar with the downgrade process right now if you think there's even a slight chance you might want to drop back down to an older version of iOS 8.
