Hello, i have an iphone unlocked with tmobile sim. I dont have any data plan whatsoever. Like others with no plan, when i try to go to a webpage with EDGE (APN epc.tmobile.com), it redirects me to their Tmobile upsell page. however, I have tried this website called tmobilepro.redirectme.net, with wifi off and using tmobiles APN. This led me to a tunneling site. Through this site I am able to go to anywebsite i want on EDGE! My question is is this really free, or will I be charged later on?
