for those still having the facebook problem:
I, along with some others (though nobody it seems on this board) are having the same problem with the facebook app that everyone was having when it was released. That is, only have two permissions appear on the application menu on the facebook website, therefore having very limited access with the zune hd facebok app. Well, I spoke with customer support today, and they said it's a known issue, and a fix is in the works. What form that fix may take (firmware, app update, etc) they didn't say. So there you go.
If this is ofn, appologies...
