There are tons of iPhone wallpapers out there by now, but this set is extra special-- it's a set of satirical wallpapers, designed, says Josh, to "show off the true power of the iPhone" by replacing the standard loading screen with one of your own. Did you know your iPhone could attract total strangers, create Universal Healthcare, or even resolve global warming? It can-- just as soon as the loading bar completes.
I think my favorite is the one shown here, though. Sure, since it's just a picture, you could say that the bar will never finish, so the iPhone will never be obsolete. But as one of the people waiting for v2.0 to buy an iPhone, seeing the bar past halfway at least inspires a little hope that we're almost there.
