Understanding Permissions & How to Change them?

As always, thanks Alex! I Repro'd and subscribed to the issue.

Facebook has another bug right now with viewing app pages on mobile devices. App links used to redirect to the Activity or Wall page, but now the show a 404 error page with this at the top: "The page you requested was not found." Facebook mobile was never very good with handling with their applications, but this new bug leaves the user stranded and makes us look unprofessional. Hopefully facebook can fix both these issues quickly.

And yes, I still need to figure out how to fetch a users Likes. I've searched for a way to do this, but I can't seem to find any tutorials... maybe querying for facebook application data could be a feature JFBC v4.3...
