How do you change Web Session from T-Mobile to AT&T

[SiruDrawoh]

Hi, this is my first thread/post thing. I just recently downloaded and flashed the Kristal White and iPhone Monster Pack and while it works perfectly, the web session is set to the T-Mobile Web Service. I need a way to change it to the AT&T Web Service so I can get online and receive pictures and other things that the Web services are used for. Any help would be greatly appreciated.

Thank you for the help! :)

Okay, my phone won't download the app. Keeps saying authentication error. I have the web sessions, but I don't really know what to do with them to make my apps use a certain one or receive SMS messages. Hmm... Getting someone to send me a SMS now.
