    I have an ATT iphone 4 with firmware 04.11.08 that I am trying to use on t-mobile. Ive jailbroken it already and now I am trying to unlock this thing using SAM but i reach a point where in itunes it says sim card cannot be activated. Ive tried just about everything and i heard that apple just came out with a block on itunes for unlocking iphone4 with firmware 04.11.08 2 days ago :mad:! is there anyone who can possibly help me out on this issue?! Anything helps ! Thanks .....

    You cannot software unlock it. Apple blocked the sam unlock method a while ago.
    I dont even think there's a gevey that unlocks that baseband either.
    Try getting it officially unlocked by contacting the carrier its locked to.
