upgraded my iphone 4 AT&T locked to newest iOS 5.1.1 with baseband 4.12.01 and it used a Gevey. Worked fine...until I decided to make the stupid move of upgrading... now I have it locked and have no other phone. I am not in the US, can I get anyone to answer me if I can ask someone to buy me a Gevey that unlocks my phone with the new configuration? Can I unlock with AT&T without being a customer...? Thank you all, very much for any help!
