This is one of those iPhone apps that manages to be pointless but cool at the same time. Tin Can essentially turns a couple of iPhones into old-school modems, allowing you to send and receive text messages using sound, instead of a network connection. Of course it’s not exactly a very useful alternative to a 3G or wi-fi connection since the iPhones basically have to be sitting about an inch apart, or as long as the included headset cables will reach. So there’s a good chance you’ll not only be able to talk to the person you’re communicating with, but you’ll probably be able to see their screen as they’re typing out a message. So whether or not you think you can squeeze 99 cents worth of fun out of it is up to you.
