I'm trying to get my 770 to connect to the internet through my Samsung SGH-D407 mobile phone and USA Cingular (AT&T) provider. The 770 connects fine with wireless and even a co-worker's Motorola RAZR phone (Cingular also). But the Samsungs are booger-phones and need much hacking to work.

I've pieced together various files from sources on the internet and have this output from the pon command. I'm hoping someone can help me interpret this:

AT+CGDCONT=1,"IP","WAP.CINGULAR"
