i have the 700 bt that came with the 2.0 already installed. My phone is the sprint windows based treo. Everything works except the phone transfer. It only tranfers the same 7 numbers which were the numbers in my speed dial #'s. I erased the speed dial numbers and still the same 7 numbers. VR works fine for the numbers it transfers and works fine for dialing numbers i say. Also it did the freeze thing that only allowed the volume knob to work.
