Hi everyone, I thought I'd make a post here to see if anyone had a problem recently with their iPhone as I've been running around in circles with Apple's support website. I have an iPhone 4 running latest iOS 5 and am using Wi-Fi Sync for iTunes. Today I turned on my iPhone to find all the purchased apps had just disappeared without any kind of warning. It was as if I had restored the phone to factory default via iTunes (which I had not). I plugged my phone in to the power and it started wireless synching and put all the apps back on, however, their settings had all reverted to defaults and I'd lost a lot of data! I then plugged my phone into my macbook and actually restored it to factory settings and then restored from yesterday's iCloud backup which seems to have restored all my settings in all my apps back as they were, however something very very very strange happened. While it was copying it popped up the log in prompt for my Apple ID which was shown and I put the password in. Then a minute later the prompt popped up again, however this time it didn't have my Apple ID - It had someone else's!!!! - email@example.com!. I didn't touch it and went to Apple's website for help but in vein. I then went back to my phone and the mysterious prompt had disappeared. I have absolutely no idea who this Apple ID belongs to and how it got onto my phone! But do you think it's a problem with Apple's server? Or has someone managed to hack my account? I have a very strong password which I only use for accounts with financial information so if someone has hacked this I am quite worried! Has anyone had an experience similar to this with their phone seemingly wiping itself and then a mysterious Apple ID appearing?
