I am new to this and I'm confused. I have a Nokia 6600 and have downloaded the PC Suite software for this phone, but I do not have a bluetooth enabled PC or infrared port on my PC. (Dell Dimension 2400) Do I now also need to purchase Microsoft Wireless Optical Desktop for Bluetooth and install that before I can connect my phone to my PC? If so, what version - there are so many - Elite? Comfort? 3.0? Thanks for your help.
