Ok I think I followed the Iclarified tutorial to the letter to unlock an 1stGen Iphone with 2.2.1 firmware. The only thing I didn't do was download the 2.2.1 firmware that is in most tutorials bcuz I just used the update from itunes. Everything works with quickpwn and i JB and supposedly unlock with no problems except when I try to add a SIM card from tmobile I get a message saying something about not being able to read the SIM card and to connect to itunes. I do that and itunes says that the card is unsupported and i should find a supported card. I do something wrong somewhere?
