See, it’s things like this that get me super excited for the App Store. The app is called Friend Book, and it takes the iPhone contact list and adds a bunch of fantastic features. You get thumbnail images for contacts that you have pictures of, an alternate view that allows you to tap on a face to dial. However, what I love is the Handshake feature. Using the built-in GPS, it determines if two iPhones are in the same place running the apps trade function. If they are, and both phones shake, information is traded. How cool is that? This is going to be one of the first apps that I download as soon as I am running iPhone 2.0 software.
