I'm having a problem with my HTC Desire and bluetooth. You switch on bluetooth, and connect your device. This works fine. Make a call, and it works fine. Then, later you receive a call and answer, but the audio doesn't come through the bluetooth but the handset itself, even though the handset is showing bluetooth as on and connected. This is a major problem for me, as I'll be in the car and the phone will ring, I'll press the bluetooth to answer, and can't hear anything as it's coming through the handset instead. I have no idea why it's happening, anyone else had a similar problem? This happens with three different bluetooth devices so it's not a device issue.
