iPhone only: When you see a book, CD, DVD, or game at a friend's house you want to look up and bookmark instantly, fire up SnapTell Explorer on your iPhone or iPod touch and take a photo of it. Similar to a bar code scanner (except you photograph the item cover, not its bar code), SnapTell automatically looks up your item and gives you links to Amazon, Barnes and Noble, Wikipedia, and straight-up search engines so you can compare prices and find out more about it. SnapTell's results aren't 100% accurate—once it gave me a strategy guide result when I photographed a video game cover—but everything else I tried it on, the results were spot-on. (Though you can bet an Australian bar code might throw it -- LH AU ed.) Here's what the result for the Halo 3 photograph looked like.
