I come from Blackberry and I usually like knew if this is possible or not I did was go through AT & T, which has connected with the Department of Liberation, had entered some key inputs and you have the unlock screen, Enter the code and your done bingo I am planning a trip abroad, and I would unlock the phone before making the trip.
Obviously, Android is different from the Blackberry. Does anyone know if you can unlock the Atrix2, without having to install a different SIM card from another carrier, there is a key input sequence that gives you the chance?
