Starting with Facebook Graph API v2.0 friend-ids are app-scoped.
So how can I launch the Facebook info/wall page of a specific user's friend using the "fb://" scheme (as explained here: https://stackoverflow.com/a/6638342/819355) with an app-specific friend id?
Looking at Facebook's app manifest it seems they still register to the "facebook://" and "fb://" schemes, so I hope this is still somehow possible.
