I recently bought an iPod so that I could test my own HTML5 games on iOS, and while looking around I found this HTML5 app:
http://www.apple.com/webapps/games/goldnuggets.html
If you load that page from an iPod or iPhone, you'll be able to play the game.
What I found memorable about this app is that when you try to load it, it forces you to 'install' (save) it to your homepage before you can play. The benefit of this is that the HTML5 app gets the full screen area to work with when launched from the homepage, just like a normal iOS app (as opposed to being covered up with the address bar and that command bar at the bottom).
I was wondering how I can check if the app has been added to the homepage (not the actual "add to homepage" function - which according to this thread is not possible Javascript for "Add to Home Screen" on iPhone?).
I could certainly use an extra 100px, and it would allow me to easily create an iOS version and HTML5 version with matching interfaces, and a better user experience.
Any ideas? Google search turned up nothing for me.
