How to go back to ACTIVATED 1.1.2 to 1.1.1 and UNLOCK?
Any recomendations will be appreciated, i ve been trying since last night. Its my friends phone and it seems like he bought it in week 27 activated it with AT&T then updated from itunes as the upgrades come along. How can i unlock this phone? I ve tried going back to 1.1.1 then baseband was 4.... I ve tried to virginize it and flash it back to 3.... but i couldnt.. I dont want to try anysim because it can mess up the whole thing. Maybe it wont but i want to make sure that i am safe with it.. So if anybody had this problem or anyone who has a solution for this, please help me.. Thank you
