On the iPhone 5 list you have 9 versions of US capacity & carriers and then just iphone5 international.
Why not just put 3x iphone 5 size options for international as well or really just lose the carrier options. It is very narrow minded to think that your market is limited by your borders.

I'm in the US for a few weeks and have an unlocked iPhone 4S and desperately need talk, text and mobile web service from any company EXCEPT AT&T.
