lately i have been havin problems with coverage with my phone. i have been livin in a house for like 3 months now, i never had any problems till now. i dont have 3g in my area and untill recently i would have EDGE but now i have been gettin gsm or sos. i called att and they said im in a good coverage area and they guy told me it might be a sim card issue. i went to att and the replaced the sim card. but that didnt fix the problem my phone keeps goin into SOS mode or gsm. does anyone have any ideas how to fix this. i have upgraded to 5.0.0.238> i dont think its the os bc it worked perfectly for like 2-3 weeks before i started to have this problem
