Apple seems to have broken a couple of things in Safari for a web app launched from a touch icon.
1) scaling of web apps
We have the following header:
<meta name="viewport" content="width=device-width,user-scalable=no" />
In 3.2, this scaled the display smaller.
In 4.2, it scales portrait mode but not landscape mode, so the application no longer fits when the iPad is rotated.
2) startup image:
<link rel="apple-touch-startup-image" href="img/loading.png"/>
In 3.2, this showed in both landscape and portrait mode.
In 4.2, the image is displayed only in portrait mode.
Are there work arounds? As yet undocumented meta elements?
