If you’ve started to build web applications for the iPhone, why not create your very own icon? Since the iPhone now allows web sites to be bookmarked from the home page, it’s easier than you think.
1. Make sure you are running the latest release iPhone firmware (version 1.1.3).
2. Create the icon at 158 X 158 for maximum crispness.
3. Upload to your root directory.
4. In your HTML header code add:
<link rel="apple-touch-icon" href="/apple-touch-icon.png" type="image/png" />
