My phone will not make any calls. says it is dialing but never rings and eventually stops calling. when trying to call my phone the phone will say network busy and beeps. however...able to send and recieve sms and mms messages. I think i messed something up in my network/connections settings. usually when i tap on the network icon on top it will sat AT&T gprs 3g but now just says AT&T.
