i have just recently gotten a 3gs and i need to know how to block the data. at&t does check ups and activate the data plan when they know yyou are using an iphone. how do i block it? i know it seems useless to have an iphone without data but i cannot afford it, and i got the iphone at a reasonable price. my friend sold it to me for 50$! so that is much cheaper then getting an itouch. i would only like using the phone and wi-fi. the data plan has been activated twice and i had to contact to get it removed. For the iphone 2g, i just usedd a fake apn application and it worked. i just recently got the 3gs and did the same thing, but i got an email saying they added the data plan, so i had to remove it. is there any way to use an iphone 3gss without having to pay for data plan, and not having at&t catch me using it and automatically adding the data plan?
