An extremely cool new feature (for me) that Apple did not mention, has been found in the latest iPhone software update (2.1).

An AppleInsider reader discovered that a feature in the latest 2.1 software update creates the ability to launch properly formatted web applications in full-screen mode without the Safari wrapper, making it appear as though it is a native app.

The new feature requires the web developer to add a special piece of code that enables full-screen mode. To view a demo app in full-screen mode, this is what you’ll need to do:

-load the demo app in Mobile Safari on your iPhone located here
-Hit the “+” button at the bottom of Safari
-Select “Add to Home Screen”
-Save the App to the Home Screen
-Tap the icon that was just saved to your Home Screen

Voila! The app should now start in full-screen mode. The only difference now is that you’ll notice a web app will run slower since it is not an installed application and loads graphics from the web. Pretty cool though, eh?
