For example, the following URL shows the app in a tab:
https://www.facebook.com/just.to.get.a.rep?sk=app_203403406338325
But when on a mobile device it redirects to the mobile site and does not show the tab or even have a link to it:
https://m.facebook.com/just.to.get.a.rep?sk=app_203403406338325
I even have the application tab set as the Default Landing Tab for this page, but cannot get the pap to show for the page. Is there another format we need to develop for the App to support mobile? Ideally we would like to show the tab on iPhone app and other mobile viewing.
If you're in control of the link the user clicks on to reach your fanpage/pagetab-combination, then try adding a GET parameter ref=ts
h++ps://www.facebook.com/just.to.get.a.rep?sk=app_203403406338325&ref=ts
Apparently this prevents the redirect to the mobile version of facebook.
