Help, no, but mutual complaint, yes.
My new HTC Wildfire tethers via cable but also not via Bluetooth. It cosies up to my car OK and swaps files with that, but doesn't want to know the PC for anything unless it has wires to push the electrons through.
My previous Nokia had no trouble at all, in fact that would ONLY tether via Bluetooth, more-than-possibly because I lost the cable ;-)
Tony Draper is right, wouldn't have happened in the days of steam !
