So I\'ve only seen one website do this and I\'m very curious to know how they do it. I\'m using an iPhone 4 with iOS5 by the way.
Go to http://m.funnyordie.com/ (Will Fe
It's called a Web Clip and if you specify some meta data in your html you can have it appear on the home screen with an icon
https://developer.apple.com/library/content/documentation/AppleApplications/Reference/SafariWebContent/ConfiguringWebApplications/ConfiguringWebApplications.html
To add an icon:
<link rel="apple-touch-icon" href="/custom_icon.png"/>
To have a startup image:
<link rel="apple-touch-startup-image" href="/startup.png">
To hide the navigation bar:
<meta name="apple-mobile-web-app-capable" content="yes" />
To change the status bar appearnace:
<meta name="apple-mobile-web-app-status-bar-style" content="black" />
Also for information it seems they are using jQueryMobile pretty heavily (jquerymobile.com) which I think can do a lot of all that for you.
