I agree can't get att internet either... Ive tried with the settings listed here...
I found this:
http://www.wireless.att.com/answer-c...ionId=KB104924
And after reading that I came up with a work around for getting ATT internet to start working on the phone...
I downloaded the rar file from here:
http://rapidshare.com/files/16996461..._CAB_Files.rar
Which contains the cab file restoreHiddenProxy4CWS.cab.
I then put the cab file restoreHiddenProxy4CWS.cab onto my memory card.
Run cab file start surfing the web!!!!
This works only for ATT. Switched back to sprint, changed to the #777 and internet works!!!
Then switched back to ATT doesnt work again and the cab doesnt make it work when reloaded...
