Yeah clearing the data cache like cyber warrior said gets rid of it for mine and my wife's phone anyway. I take it that it's some kind of bug because it happens periodically to my phone as well as my wife's. Also on our phone's, when you have a message it has a green one or two or how ever many number messages you have, well i have noticed that after you read your messages you have to pause on the main message screen and wait for the green number to disapear because if you don't and you back out really quickly then it will still say you have the messages in the green circle. Hard to explain in writing but just thought i would throw that out there in case you were having that problem as well.
