Full-screen Web apps feature with latest Apple iPhone software
There is an unpublicised feature that has been introduced by Apple for the latest Apple iPhone 3G software update with the ability to save Web applications to the home screen, and then have them launch in full screen mode without the Safari wrapper.
An AppleInsider reader who noticed the matter believes the undocumented feature came with iPhone Software update 2.1, and went even as far as to create a demo app for iPhoners to try out.
So here’s what you need to do… Load the demo app in Safari on your iPhone…hit the “+” button at the base of the Safari app…select “Add to Home Screen”…save the App to the Home Screen…tap the icon that was just saved to your Home Screen…and the demo App should load in full screen without the Safari wrapper.
