Can anyone recommend a iPhone 6 AT&T unlock service. I tried 'www.officialiphoneunlock.co.uk', they said the phone had been unlocked but a T-Mobile sim wont work. Guess its a scam. The phone would still obviously be on contract since the iPhone 6 is brand new. Any suggests on a service that can perform an unlock would be greatly appreciated...I move to Berlin next month and it would be nice to have an unlocked phone ready. Thank You in Advance...!
