I used the instructions here and was successfully using my pearl to connect through Cingular/ATT (though I would get kicked off if it was idle for more than about 60 seconds). About a week ago, the connection really bogged down a few times. I tried rebooting the computer, then eventually I got the same "A modem error occurred. Please verify your settings and try again." each time I tried to log on. I wonder if ATT might have changed something with this access....
