I have the Blackberry 8100 and it is currently running on old software (2002) I downloaded the desk top manager to update everything but its not working. I have plugged my phone into every port possible. Its connected by USB cord. It is showing the "charging" symbol next to the battery life, so Im assuming its plugged in correctly. But the desk top manager doesnt want to recognize or find my phone. I need to update this stuff. So if anyone can help, that would be AWESOME!
