Here's an iPhone game to play if you don't want anyone sitting next to you on the bus: Upskirt. Yes, it's what you think it is, right down to the skirt-flipping sensei with the panties on his head.
The trailer says Upskirt (which looks like it's based on this flash game) is due Jan. 11, 2011, from the iTunes App Store. Let's see if it in fact keeps that date with Apple.
