And for the sake of completeness, a link to Scott Hanselman's posting, which contains some additional tips as well:
How do I set the icon that appears on the iPhone for the web sites I create?
Depends on how much detail you want it to have, it needs to have the aspect ratio of 1:1 (basically - it needs to be square)
I would go with the Apple's own 129*129

Create a Web Clip Bookmark Icon
iPhone and iPod touch allow a user to save a Web Clip bookmark to your site on their Home Screen.
To specify a bookmark icon for all pages of a web site, place a PNG image named "apple-touch-icon.png" at the root directory of your web server - similar to the "favicon.ico" for site icons.
To override the site bookmark icon on a specific web page, insert a <link> element similar to <link rel="apple-touch-icon" href="/customIcon.png"/> within the <head> element of the page.
The bookmark icon dimensions should be 57x57 pixels. If the icon is a different size it will be scaled and cropped to fit.
Safari will automatically composite the icon with the standard "glassy" overlay so it looks like a built-in iPhone or iPod application.

Specifying a Webpage Icon for Web Clip
iPhone OS Note: The Web Clip feature is available in iPhone OS 1.1.3 and later. The
apple-touch-icon-precomposed.pngfilename is available in iPhone OS 2.0 and later.
You may want users to be able to add your web application or webpage link to the Home screen. These links, represented by an icon, are called Web Clips. Follow these simple steps to specify an icon to represent your web application or webpage on iPhone OS.
To specify an icon for the entire website (every page on the website), place an icon file in PNG format in the root document folder called
apple-touch-icon-precomposed.png. If you use
apple-touch-icon-precomposed.pngas the filename, Safari on iPhone OS won’t add any effects to the icon.
To specify an icon for a single webpage or replace the website icon with a webpage-specific icon, add a link element to the webpage, as in:
<link rel="apple-touch-icon" href="/custom_icon.png"/>
In the above example, replace
custom_icon.pngwith your icon filename. If you don’t want Safari on iPhone OS to add any effects to the icon, replace
