I can't tell you abou the media thing.
But as for facebook, try uninstalling it then re-installing it. After that make sure you facebook email is the same as the blackberry email, for example; your log in email for facebook should be the same as the BIS email you get (ex.
![[email address]](?emailimage=2b1b52b0486f97c8254794fcbbde76fa)
) and make sure on the facebook site your notifications are set correctly.
