Called Hotel Radar, it uses your iPhone 3GS's compass to locate deals around your current location. Just point your phone in any direction, and the app will sweep the area around you, finding available deals like active land mines. Touch the price, and you'll be provided with prices, ratings, reviews, and availability in no time flat. It's free, and I have to admit — besides being fun to play around with, the opening sequence with William Shatner is kind of awesome.
