Looking for success & fail stories having no-data plan on iPhone. I've had the OG iPhone since the beginning. We also have a 3Gs. We are considering 1 or 2 iPads. As my OG iPhone slips away tech wise, it is still a great phone and I don't need another. I am considering canceling my data plan to support a potential 3G iPad data plan. I would like to use my iPhone on wifi but isn't there a great chance I'll accidentally connect to EDGE?
