I have an IBM which has bluetooth. I recently purchased the Plantronics 320 bluetooth headset, and it works with my motorola phone. Now I tried to use it with the X31. I went to the bluetoot icon, and pressed Add, and put the headset in pairing mode but the computer does not find it. I called plantronics and they said that this has to work unless the computer's bluetooth does not support headset profile. I called IBM and they say (at least the person I spoke to there) that it does support headset profile. My question is does anyone out there know if the X31's bluetooth does in fact support headset profile?
