The Apple iPhone isn't just pretty, it's useful, too. One of its coolest features is that it can be customized with hundreds of free Web applications. These applications allow you to check in on your favorite social-networking sites, receive RSS (Really Simple Syndication) news feeds, watch videos and play games -- all on an interface that's made for the iPhone and iPod Touch.
Web applications, also known as Web apps, don't require any special software downloads. Since they're Web-based, they're accessible through the iPhone's Safari Web browser. Simply type in the application's URL, and you're there. If you like a Web app, you can easily add an icon to your iPhone home page for easy, one-click access.
