Fast,
I can't connect to my ISP either. I'm just using the included PPP Connect app, and it dials the modem correctly, and somehow does some sort of sending and receiving periodically. It even comes up with an IP address, but sometimes the IP isn't in the normal range of IPs from this paricular ISP. Strange... I'm going to keep working on it. And maybe tell Apple if I'm sure it's not my fault.
JL!
