My pal is looking to get an iPhone and use it on a prepaid (GoPhone or T-Mobile) plan. The thing is, he does NOT want any wireless data available. Does anyone know how to block data on either carrier? I know on AT&T it's quite easy if you have a plan, but I do not know on a prepaid plan. I have no idea how you'd go about it on a T-Mobile prepaid plan. And I suppose he could use a program like BossPrefs to block data, but I don't want him to have an issue with it as I've heard some have. Which will be cheapest and easiest for him?
