I also got my 770 from Woot and wanted to pair it with my Dash. I read this thread and got a bit overwhelmed. Finally I did some more searching and found a file that adds the DUN profile to Windows Mobile 6. It worked fine for me. Now I can use my Dash data connection whenever there is no WIFI around. So if that is all you are trying to do, I recommend using the file. I attached the file that I used.
