I've got an unlocked iPhone with T-mobile carrier :cool:. Now... if I put back my AT&T Simm card and I do the upgrade through I-tunes, what will happen to my iPhone ? Is it going to be only locked and upgraded or will I-tunes "burn" :)embarrassed:) my phone ? Does somebody know the answer ? Thanks in advance....
