i am about to buy an iphone 3g 16gig and i was asing my cuzin who works for att and he said that i could like mod/unlock/jailbreak my phone to use a medianet patch so i can use medianet instead of the iphone one(which is the exact same dam thing just way cheaper!) and thus saving me some moeny. he said it was done succesfully to his friends iphone 3g and it worked just as good as it did when it had the normal iphone plan. have any of you guys done that?? or heard of it?
