It'd be great if Best Buy carried iPhones.
They're already opening up sections devoted to Apple so it would make sense to carry one of their biggest products. It would also ease the lines at AT&T and Apple stores.
A friend of mine is a Best Buy Mobile manager and she said that they have no plans on selling the iPhone any time soon. The only stores that will be handling them will be AT&T and Apple. At least that is what she was told at the training she went to back in May.
