I'm an ATT customer. When I text "*639#," I get the following message: "As a valued customer, we can offer you an upgrade with a new 2 year commitment and an $18 upgrade fee" I've never owned an iPhone. Does this still apply to iPhones? So if I get the 16GB, I will pay somewhere around $218? Where do I preorder from online? The Apple website or ATT website? Thanks.
