    Hey, today I purchased a 2nd hand iPhone 4, I'm not sure the baseband or the firmware or anything because the screen says "Insert a Valid Sim with no PIN lock to active phone" , it also give me a emergency phone call option ...

    My problem is that I have T-mobile and the man I bought it from told me the baseband was not 4.11.08 or whatever that baseband is that cant unlock, he said it is unlockable, I dont kno where to start with unlocking the iphone? Can someone point me in the right direction ?
