You don't have to just use a mobile phone to access the mobile site through the WiForums interface - it can be done through any normal internet browser, at least it can using Safari/Firefox on a Mac.

Try visiting: http://mobile.flyertalk.com/BrowseForum.php

You will see no forums.

And: http://mobile.flyertalk.com/HotTopics.php

Where you will see that the threads are a few days old and get the error message: "The requested page does not yet exist".

I know WiForums released a new version (v3.9.4) on Sunday - maybe that has a fix?
