Q: On my Nokia 6680, I get a message about the camera being in use whenever I slide down the camera guard. Is this an error? No, this is not an error, per se. When you slide the camera guard down, the phone automatically starts the camera application. If Cellicast 1.0 is already running, the Nokia camera application receives an error. You can ignore this. To avoid this in the future, slide the camera guard down before starting Cellicast 1.0.
