You're seeing an open source project to make universal interfaces for iPhone using technologies like HTML, CSS and all the capabilities of the phone.
This framework was made for that: make life easier for the developer, letting you run a few elements of HTML to build complex interfaces same as you'd see on the iPhone.
Look into the source code of this project, analyse each example and performs your own tests with a simple webserver and an iPhone Simulator or, a real iPhone. We're working to make more interfaces and add them to our framework for sharing with everyone.
Anyone can collaborate in the project, simply send me your edits to firstname.lastname@example.org and then you add the SVN project.
