I have a T-Mobile Wing phone and I'm able to use edge to do instant messaging and stuff from it, but when I put the Sim card in my iPhone it doesn't let me go to any sites or check my mail. Any ideas? I installed the $5.99 T-Zone hack, not sure if that's the right plan. I have tried APN: wap.voicestream.com, username and password as guest. I've also tried APN: internet2.voicestream.com, username and password as guest. Any ideas?
