I've tried multiple chargers so that rules out any issues with the way its charging in the holster. I did try charging the device using the usb cable and it seems to function as it should, it even syncs properly which again leads me to believe that this is more than a defective usb port. I am coming to the conclusion that there is a software glich in which the device going into standby causes the blackberry to think the media card has been removed and the device resets itself because of that. Even this idea still raises the question of why it would charge fine in the holster. I would think that the device is still in standby while in the holster. Although I've noticed that the blackberry has different "modes" for magnetic holsters (example. ring tone settings for in holster, out of holster.) so perhaps this could be why it only works in holster mode. who knows.... i'll try a software wipe to see what happens.
