Hi, i have a iphone 3G with OS 4.0.2 unlocked and jailbroken. I use t-mobile for the wireless provider, i understand back then you can use the t-mobile internet on the iphone for $10, and still some ppl still do. But i cant seem to access it. it keep redirecting me to upgrade my plan to the $30 one. Is there something im suppose to do?? Thanks so much!!!
