Isn't tethering a wifi and not bluetooth function? If I turn on mobile hotspot on my D4, I can "see" the phone on my laptops wifi "available networks" list. If one can tether via bluetooth, its news to me. I havent been able to figure out how to bluetooth stream music from my D4 to laptop, like I could with my earlier Droid. I suspect its a driver issue with Win 7 /32.
