Does apple stores accept cash for the new iphone 3G?

I'm pretty sure apple stores do not sell the new Iphone. They are exclusive to AT&T and require a 2 yr contract.

On July 11, 2008, Apple will release the iPhone 3G in twenty-two countries, including the original six. Forty-eight more are expected to follow in the months afterwards.[1] In the United States, purchasing the new phone will require signing a two year provider contract with AT&T
