This was sent our way along with a tip saying almost a dozen people had successfully processed US apple.com iPhone 3G S orders using this hack to avoid AT&T's online contract sign-up.
It doesn't get you the subsidized $199/$299 price, nor an unlocked iPhone, of course, so don't get too excited.
We have no idea if it actually works either -- if orders placed this way will actually ship, or if AT&T goons in black will show up at your door for a little curb-stomping contract reminder. We obviously can't condone it either, so we link to it strictly for educational and entertainment sake, knowing our readers are all responsible adults. Right?
