I have a 1st Gen iPhone that I'm using for T-Mobile and have the $9.99 data/messaging plan. I can connect to the internet, use Safari, check my email, etc. in Marinette, WI and Menominee, MI but can't seem to do anything outside of this very limited area. Everywhere else says "cannot connect to internet" or something to that effect. What is happening, why is it doing this, and how do I make it work everywhere? Currently I have epc.tmobile.com as APN, but I've also tried wap.voicestream.com It only seems to work in those 2 cities. HELP!
