I'm posting this in case anyone else is encountering the same problem...

I've upgraded to a Nokia 6600 and attempting to connect it using the PC Suite software that came with it. The IR connection is established, no problem. I go into the PC Suite software and it prompts me to name the phone, using "Nokia 6600" as an example. No matter what I enter I am told that it is not a valid name and it won't let me into the PC Suite.
