Ok I have an unlocked Cingular 3125 that I use on the T-Mobile network however I cant get WAP internet to connect even thought I have the settings correct for T-MobileWeb and I pay for the service. Also this stops me from sending and receiving MMS messages. It's even CID unlocked. I've searched all over the web and all the suggestions match the settings I have. Can anyone tell me what the problem might be?

go to the Cingular website and look for the proper settings for your phone.
