Problem solved - I found to solution on xda here:

I just needed to call and ask for a DMU update, argue a little with the guy, and voila! The way I found what I needed was by searching for the actual error code (duh on my part) I was getting: "Error Code 11, PPP Connection error"
That brought the solution right up!
