go to facebook.com and it will take you to m.facebook.com then just delete the m and it should take you to the full site. None of the games or videos will work though.
Login to the r facebook site, and then on the left hand side there is a URL for MORE, click on that. Then scroll down and there is an option that says DESKTOP SITE. Click that and you should be there. I just tested that, and it works fine. Hope that helps.
