It sounds to me like you have to reload the OS on your BB. Open DM, plug in the 9700 and reload.
As an aside, my 9700 got wet about a month ago. At first, everything appeared normal, but then....ANTS! Sorry, couldn't resist.
Actually, everything now works except my camera. I'm lucky that's all that is bad. If anyone has any suggestions on how to get the camera to work again, I'd be all over that.
