Question. If something happens to my iPhone be it the front glass getting shattered and I want a replacement. I know Apple will replace my iPhone 4 for $149. But will I be able to retrieve my iCloud account from that replacement being as though the replacement will be iOS 5.1.1?
How does this work?
If you're asking whether you'll be able to restore your iOS6 iCloud backup onto your iOS5 iPhone the answer is no.
However theres nothing stopping you from installing iOS6 onto your new iPhone and then restoring.
