Suspected usability issue in PDA portal - 86% bounce rate

Site analytics show a 86% bounce rate and 84% exit rate for the PDA portal. This and comments to the support queue seem to indicate that users may be confused about the intent of the "Switch to Full View" button.

Users have no obvious return path to the PDA version once they select the "Switch to Full View" button. You actually need to force quit the (iPhone/iPad) safari app then reopen the Sakai URL so it will again auto-detect that you are using a mobile device. Previous to iOS4 you could only have one application open at a time, so clicking the home button would quit the application. In iOS4 the default behavior for most apps is to stay open in the background so in that case you need to force it to quit the app.

Manually quitting an iphone app:

1) Double click the home button.
2) Hold down the app icon till it starts shaking.
3) Tap the red icon with the minus sign above the app icon.

As a temp solution we may want to put a direct link to the pda portal in the MOTD:
