Has anyone has any luck with voice dialing via bluetooth? I have tried several bluetooth headsets and haven't found one that pairs with a handsfree profile to allow voice dialing via the bluetooth's microphone. So when I try to voice dial it doesn't recognize what I say and will "guess" and dial random people or just random numbers. I'm just trying to see if there is a headset out there that will work with the THunderbolt for voice dialing. Anybody have any luck?
