this makes no sense

Regardless of browser (at least between ie and firefox), I can get to the payment page to preorder an iphone on the att site only if I don't go ahead and attempt to, oh, specify anything about the plan (which would really be stupid). Otherwise, if I go to change the plan, the browser either hangs (firefox) or directs me to a black screen when I hit "add to cart".


Siiigh, wish I knew if I'd still have the option to keep unlimited data if I went to store....Sigh.
