Another question...
As you all know the Xperia Ray comes preloaded with Facebook. Each time I go onto my Facebook there is a notification that a newer version of the app is available. Should I be downloading this newer version? Thanks!
I would suggest downloading the new version of the application as this may provide better functionality and better user expirence.
and if you dont like it..
go to settings > applications > manage applications > all >
search for facebook..select it and select uninstall updates 
you'll be back to the normal version or previous version..
