I've had my V3M for a few months, and someone had it before me for I'm not sure how long, and it has worked flawlessly until recently. I was composing a message, and the phone locked up. I took out the battery, put it back in and restarted. I got a field of snow on the display, so I took the battery back out, and back in, restarted, and it worked fine. However, my girlfriend just called and asked me if I had received any of her text messages, as she sent a couple, waiting on my reply. I didn't get them. I sent one to her and she got it, but nothing in return. I sent a few others, and no reply either. Is the phone on its way out or it just a simple fix? Its on Alltel, and hasn't given me any trouble until now. Any advice or insight would be greatly appreciated.
