Do you know that you can create mobile apps using HTML5/CSS3? In fact, a lot of the apps you use on your iPhone is actually not a real app (Objective-C), but a web app created in HTML5/CSS3 and jQuery to look like and function like a real app.

For example, open http://m.facebook.com/ from your computer and from your iPhone. You will see that they are actually both the same page and the same User Interface. And that’s because Facebook is using HTML5 and CSS3 for their mobile app.

You can make it to look like a real app by using the Gradients in CSS3Generator to create a gradient that look like a real iPhone app.
