hello, i have a jailbroken iphone 2g running on firmware 3.1.2.

i wanted to know if my tzone edge $5 plan can work bec. there is no tzone hack in cydia.

i had it working when it was 2.1.2 but now that its 3.1.2 i would really appreciate full step by step instructions for a novice.

i tried changing APN to etc.tmobile.com but no luck
any advice.
