im looking to get an iphone 3g. i had a few of them, but have always ended up selling them because i am on a family plan and it doesnt work out well. i have jailbroken before, and i know about how to use cydia to fake apn numbers. what i was wondering is if there is a way to fake an apn number or block 3g (and edge if the phone would revert to it) on an iphone 3g so that i would only be able to use internet while in wifi WITHOUT jailbraking the phone. if this has been asked before, i am sorry but i did search lol.
