I Got the iPhone 3G from my friend. He traded my iPod touch 2G for a black 16GB iPhone3g. I restored it and whatnot, and its working fine. I have a GoPhone Pay as You Go sim and it works fine for texting and calls. But what about internet. I Heard wherever i can get 3g, the 3g is free. also, does the turn-by-turn GPS in Maps charge for internet usage? or is it free since its GPS? thanks for any replies received.
