Here’s an interesting tip from AppleInsider. If you include this meta tag in your iPhone-optimized web app:
<meta name="apple-mobile-web-app-capable" content="yes" />
Then, if you use the Add to Home Screen feature, it will launch as its own standalone app, with no Safari browser chrome. It’s a way to make site-specific browsers for the iPhone. They run as their own processes, outside MobileSafari. Update: Here’s the documentation.
