I had that happen to me the other day. It was the first and only time it happened. I pulled the battery out while it was on, booted it back up and it has worked great since. I think it was a Verizon issue because friends i talked to noticed their signal bouncing around in that area. The phones were 2 Moto Droids, Droid ERIS, Blackberry Tour, Incredible, and an Envy 3.
