new to the BB world here, and i have a bit of a hair puller here...
I can receive SMS Messages, but i cant reply, yet i can forward to received messaged.. i called t-mobile and had them re-sync to the network and nothing.. im going crazy here!!!
First try a battery pull. With the phone on pull it out for 30 seconds and put it back in. Then go to options. Sms text and change the network to send over to gprs hit the menu button then save then change it back to gsm
