This method ( http://talk.maemo.org/showpost.php?p...&postcount=103 ) is worked, repos updated, facebook-installer installs, but when I open it, it opened the app manager, and I've got error from it about it can't find the right packages or something like that I suppose. (It's trying to find the old Nokia repos, it ignores the backup ones).

When I want to install manually the Fb packages one by one, I came to the usual stuff: feedservice2 is not installable.
So it's not a repo issue, this package, if it's ever existed, it's disappeared by now.
I'm most certainly don't want to reflash my device just for trying if Fb is working on a fresh system or not.
I just wanted this one simple stuff to working correctly, but I think in my level of noobism, it's not possible.
