Alot of times, the camara actually pops loose out of the socket that is it plugged into. This can happen if the phone is dropped. If you remove the battery door, you can actually put your thumb over the lens of the camera and hold on to the front of the phone and push in on it with moderate force. You can actually feel it click back into place. If that doesn't work, you might need to send it to PDA Repair World or something to have the camera replaced or the board repaired.
