I was looking on the marketplace and it states Facebook for WP 4.0 was released on 27th October 2012 logged out, but if i log in, as i have a lumia 900 it then states 2.7 is the latest version. Is this update now only for WP8 customers as this has annoyed me as im having so many problems with the current version. When are WP7 customers going to get this update?
