We have a web app deployed on iPad that which incorporates the to specify the app icon on the home screen. The icon is in the root folder, and just to be sure is named apple-touch-icon.png. The app icon worke fine on IOS 4.3.3., but is ignored on the devices that have upgraded to IOS 5. It uses the (ugly) default miniature screenshot image icon.
Works fine on IOS 4, but not on IOS 5. Any thoughts?
