I'm currently uneligible for an upgrade and am on at&t. There are two lines and I'm on a familyplan - one line has an iPhone 3G and the second is a 9.99 add-on to the basic 59.99 or whatever it is plan. I want to upgrade the lines to the 129.99 plan but is there any way to do this? I'm looking to buy the iPhone 3G 16GB but was unhappy when I found out it would cost me 500 dollars - I read of a loophole to get it for 300 but does it work? Am I better off just getting a used one or is that going to cost even more? I would love it if someone could explain to me just what I need to do to get an iPhone 3G on my current plan. Thanks everybody, I appreciate it!
