hey guys, having a quick problem. I recently switched over from T-Mobile to ATT just last week. The porting etc etc just finished up yesterday. I ordered a code from cell unlock and for the past day, have been trying to unlock my 8520. When i put in the code and click enter, it says the code has been accepted but than the phone freezes. When i do a battery pull and check if the phone has been unlocked, i realize that its still locked. I probably did this 3 times. I even updated to 5.0, but still no luck. what do u guys think the problem is? could i claim warranty on this???
