Is it not the case that when you unlock an iPhone through unofficial channels some features get disabled? I'd imagine that the issues relating to such unlocking are covered in detail elsewhere online. Have you tried searching for such info?
No, AAM is my first stop. the guy whos offering it to me has said it is possible. will ask him about features being disabled.
Its all above board. He got the phone when he was working with Apple. Now hes buying the new edition so I asked him if I could buy his old one off him.
