Samsung SPH-A800 / MM-A800

I am looking into this phone for it's mp3 capability and 2.0 MP camera (I know these are both just adequate and not stellar in those areas) and I ride a motorcycle, so the less number of devices, the better. I was looking into a bluetooth adapter to use my headset while riding, and from what I understand, the adapter performs the same as a wired headset in terms of auto-answer, etc.
Has anybody had experience with a BT adapter and used it with bluetooth and calling, etc?
I'm fairly certain this would work this way.
