That article is the only one I have seen. Although dated I believe it was for XP SP2. BTW, I have just returned my second Bluetooth USB device for my Toshiba device because, after hours and hours of work, it would not work with the BB 8700C to sync. I would allow me to connect to all sorts of headsets and whatever, but I could not get it to enable syncing the BB with Outlook 2003 on this XP SP2 notebook.
I'm giving up for now since plugging the USB Bluetooth dongle into the notebook really wasn't any more convenient that plugging a cable into the BB. From what I can see after two different Bluetooth devices (Kensington and Belkin) Bluetooth and Blackberry just isn't worth it.
