However, i just remembered something. The day my phone stopped getting service, i vaguely remember clicking on the terminal emulator app just to see what it was all about. I must have clicked somewhere on there, because suddenly i had a notification that said i had 140 new text messages (all my messages came up as new messages in the notification bar). I would try to clear the notifications, but the text message icon in the notification bar would persistently keep popping up immediately, saying i had 140 new text messages. I didn't know what to do, so i went to application manager and disabled the terminal emulator app, and this stopped the new text message notifications.
Now, i don't know if this caused the issue of not getting any service, but its the only thing outside the norm that i did to my phone. If anyone has any ideas on possible solutions, I would really appreciate your help. Thanks.
