Hello, I have a problem with my T-Mobile MDA Pro. I have updated the bluetooth stack thing so that i can use my HT820 headset. All was working fine until now but for some reason if i try making or receiving calls there is no sound on the device. If i turn bt on and turn on the headset there is sound in the headset. I have called HTC but am worried that the warranty may have been invalidated by updating the bt and also i have sim unlocked...does anyone have any ideas?
