Trying to preorder on apple.com... I have AT&T with 2 lines, one is eligible and one is not, the one that is eligible does not have an existing data plan. How can I upgrade the line with data plan (not eligible) on Apple.com?
I was able to do so on AT&T.com using "shared upgrade", but I cancelled the preorder.
