I checked my backlight settings and they both are all the way turned up. About the usb. I have made sure that it works by testing it on the alltel store demo 6800. It worked just fine. I could hear all the sound through my headphones. The only thing that was diif about the demo and mine was that it was running on an older rom from ( I think it said ) 6-22-07. or something like that and mine is running on version 3.35.671.9 from 4-9-08. I dont know.
Thanks though for reminding me about the back light settings!
