Per some random set of instructions I found on the intertubes:

http://www.unlockit.co.nz/unlockit/?p=587

I've updated the context:


AccessPointName=wap.cingular
Username=WAP(a)CINGULARGPRS.COM
Password=CINGULAR1

I still get an IP address via DHCP and name resolution is working, but
my ping,wget,ssh tests fail.

A colleague allowed me to bottow his AT&T phone. I used this SIM card
and he had the same APN and Username entered in the phone (assuming same
password, wasn't visible and he didn't want me to change it just in case
:-). His phone reported an "EDGE" connection and successfully, albeit
SLOWLY, displayed web pages.

So this suggests to me that the SIM can do IP and not just WAP. However,
it says EDGE (2G?), does ofono support EDGE? I am I off in the weeds now?
