For web apps you can set the startup screen with apple-touch-startup-image
What about for iPads?
I had the same issue as well... You need to you use a specific size of 1004*768. i explained it in this blog: http://www.amirnaor.com/?p=71
From my testing today, it seems the iPad doesn't support the apple-touch-startup-image. It's quite disappointing that the iPhone does support this in OS 3.1, and the iPad doesn't. Also, when using a webapp in a chromeless browser, the viewport isn't set properly. I do believe both are bugs or omissions in the iPad OS 3.2. Too bad :( I did ask for it at the apple forums: https://devforums.apple.com/thread/47178
It's the same as the iphone. Put a png named Default.png
in the resource folder.
I think Madhup is referring to native apps written in objective c and compiled with xcode. The OP is trying to make it work for webapps that are added to the homescreen via safari. Haven't gotten it to work so far :(
The best explanation of this issue I could find: https://gist.github.com/472519
Note that it only worked for me once I provided a startup image for iPhone and both landscape/portrait for iPad.
This will add a Splash Screen to your Web App. Below are the sizes you’ll need for both iPad and iPhone/iPod Touch, and iPhone 5. These include the status bar area as well.

If creating a Web App for iPad compatibility it’s recommended that both Landscape and Portrait sizes are used.
