I've been actually using the iphone without a data plan for about 2 months now without any insane phone bills. All i did was turn 3g and push off on the phone and removed the pay per use data off my plan. So now when i open safari or any other internet reliant app it doesn't connect.
I'm tired off all these at&t and apple drones saying why would anybody use an iphone without a data plan, maybe we dont want to throw hundreds of dollars during the 2 year contract to something that barely works, while even in major cites like nyc or chicago 3g on the iphone is almost non-existent. Or maybe we dont want to use something that drains the battery like crazy. The iphone had a pretty bad ass interface with wifi, ipod, camra, and nice touch screen to back it up. Its not just a internet device, some people just rank different capabilities of the phone higher than others, like myself i dont need a internet connection every step of my life maybe just once in awhile if i need it, and its not there im not gonna die.
