@Zero, I tried this cab previously and it didn't work...

I have however found a cingular Signed cab, extracted the XML file that is used to create the settings. This file happens to include the credentials that noone could find before...

I have a request for sk0t. It seemed like he was heading up the project to create a cab that had this info, and the ISP info inside one cab.

@Sk0t - If you decide to make a cab that does this, I think it would be best to create the same type of structure that I currently use (or setup each time I Flash). This includes 2 networks, "Cingular GPRS No Proxy" and "Cingular GPRS With Proxy" I use the two distinct networks for two different reasons. Exchange Activesync does not like being proxied. in fact it flat out does not work. thats why I keep my device connected to the "internet" using the No Proxy, and connect using the "Proxy" settings once I decide I want to browse the web at MUCH faster speeds.

I will work on creating a cab that has this in it as well, PM me if you have any insight.
