General Info and Tips:
Service Pack 2 install guide has been submitted by Andyloc, read it here: SP2 Install. A big thanks to andyloc for taking the time to write it and follow up with teacom to get the drivers. When SP2 first came out there was no support and I didn't take the time to stay on top of it.
I currently recommend anyone buying a bluetooth dongle try to get a Belkin F8T001 Version 2, or any other class 1 (100m range) dongle that comes with or has updates to Widcomm 1.4.x.x drivers.
The driver version that most companies support and that ships with most dongles is 1.2.2.16. There is a 1.3.2.7 Stack that is much simpler to use, it adds support for network bridging, which can be used instead of ICS if you have windows XP, and will allow someone to not have to move their router in order to get bluetooth network access working.
I highly recommend you download a 1.3.2.7 driver from the section on the right, "Download 1.3.2.7." If your device is not listed try a few 1.3.2.7 drivers one will typically work. The 1.3.2.7 driver will uninstall the old driver through a wizard follow the directions and it should go smoothly.
The setup I currently use: Encore BT3030 dongle (not the one currently on their site, but actually a tecom Bt3030). 1.3.2.7 drivers from bluewireless. Windows XP Pro. Wired connection to a netgear wired Router connected to a cable modem. I have the wired connection bridged to the bluetooth connection.
