Hello everybody! I have an iphone 3g and att "pay as you go" prepaid simcard. As you know, iphone 3g is a totally multimedia device which connects to the internet using 3g network without asking about that. So my iphone spended all $15 on my prepaid simcard in couple of hours while updating weather, mail and stuff. I called att cus.support and explained them my situation, they credited that money back...but thats not the point. A cus.support guy told me that there is no way to restrict iphone using 3g internet. But what do you think about that? Maybe there is existing a some type of application for iphone that could restrict automatic connection to the 3g internet? Or it is impossible and i need to buy another phone for my "pay as you go"? P.S.: I need to leave an ability to use internet through wifi access point. P.S.S.: Tried to shut off 3g mode in iphone menu, but it didnt helped. Looking forward for your replies! Thanks!!!!!
