On my Xoom at least when I access VF's web site I always get the mobile version and there is no way to navigate the site unless I force the Android browser to pretend it's a desktop browser.
Interesting though when on the home page of the mobile site, if you click the T&C's you get presented with the full site and if then you click the Business tab you get the full site experience. But as soon as you click personal you get the mobile home page and I cannot see any way to browse the full personal site from there.
