I've read this thread about 5 times as well as the thread over at xda-developers and I'm still not getting it though I think I'm close.

I have the TyTN with Black Dymond WM6 ROM. I have installed the DUN cab. I have copied the files from the modemlink zip file into the windows folder on the TyTN. I have also installed PDANet and enabled DUN (maybe reDUNdant with the DUN cab (?).

I have setup a phone connection on the Nokia 770 and paired it. When I do so, the 770 tells me that I will only be able to use it for dial up networking. I setup a network connection on the 770 for my Cingular service.

On my TyTN, then establish a connection with the Internet Sharing utility via the GPRS connection.

When I start to browse from the Nokia 770, I see it communicate with my phone as I see the phone establish a GPRS (edge) connection. However, the Nokia comes back and tells me it failed to connect.

What am I doing wrong? Is there something more I need to do with the modemlink file(s) and the associated registration file? Am I enabling too many layers on the TyTN that are redundant? I think I'm close but I know I'm missing something that is too obvious!

Help!!

Thanks all!
