This is a little difficult to explain but I'm gonna give it a shot.
I have a 8300 curve. Everynow and then I'll check my phone and the screen is blue with the Alltel logo in the bottom right corner. It's as if the phone is on some kind of standby...I just press the "end call" button and a few seconds later, it wakes up. Then a few seconds after that, I'll start getting all the texts that were sent (presumably) while it was in "standby"(I'll just call it standby b/c for lack of a better term). I can't get any calls while its in this mode (For example, last night some friends that came to meet me at a bar. They walked up and said they tried to call a few times but it went to voicemail, I pulled out my phone and what do ya know?? It was back in "standby".
I'm wondering if maybe it does this when it doesn't have service?
Any suggestions?
