Hey, i have an unjailbroken iphone 3g with those piggyback sim. I get my tmobile connection so i can call and text but no edge or 3g. I put in that ACN code: epc.tmobile.com but it doesn't work? i was wondering if its because my iphone isn't jailbroken. I dont have cydia or installer. Do i need that so i can have access to internet? I just called tmobile earlier to change my plan to have a compatible data plan with the iphone. They said i will receive the internet immediately because i had a data plan before for my g1 but i don't see any logo. Any ideas?
