My iPhone was stolen recently. I went into AT&T to get a new phone, and while there, I attempted to restore from an iCloud backup (from the morning before it got stolen). To sign in to iCloud, I had to enter my iCloud email address (the same one I use for iTunes) and password. I did that, and the restore began. However, to finish the restore, the phone then asked me to enter my iTunes password for another email address (some Australian address). So, even though I logged into my iCloud account and found my backup, somehow my email address for iTunes had changed (presumably because of whoever stole the phone). Would it be safe to restore from the iCloud backup, or should I just delete that backup and restore from a much older computer backup?
