Howdy! I'm about to sell my iPhone 3GS while waiting for my iphone 4. I'm thinking about picking up a cheapy Go Phone in the interim and had a couple of questions. 1. What happens when I have the rep switch my number over to the Go Phone? Since its a pre-paid phone, I have no clue how that will work with my current iPhone plan set up. 2. I don't want to lose my unlimited data plan by switching my number to the Go-Phone then back to the Iphone 4. Should I be concerned about the possiblity? I did try to mroogle the scenario but I didn't find anything useful. Any answers or advice would be appreciated. Thanks!
