This means users running iOS 10.3.2 can no longer downgrade (eg to iOS 10.3.1) because the ‘sign off’ an upgrade looks for on Apple’s servers before installing will no longer be given. AppleAs explained in my upgrade guide, iOS 10.3.2 addresses multiple, serious security flaws. While those already affected on iOS 10.3.2 can no longer downgrade and escape it - great. Surely one of the things on its hit list is addressing the battery problems of iOS 10.3.2. As such, while I think Apple should not have stranded users on iOS 10.3.2 before the release of iOS 10.3.3, a solution may not be far away.
