At least that's what T-Mobile tech support told me. I bought a motorola h17 when I bought the tab. It would stay connected for 2-3 minutes then disconnect. I do have a pair of bluetooth headphones (also motorola) that work and have a mic, but aren't particularly comfortable. Anyone have any luck using a bluetooth headset? Any idea what headsets are 'class 3'? edit - a little research shows that t-mobile tech support probably has no idea what he's talking about. class 3 bluetooth only has a range of 3 feet and the tab has a much father range than that. He probably meant bluetooth 3.0. Still doesn't explain why my h17 won't work.
