Facebook's apps on the app store do not make use of the option for a custom EULA, so nothing there needs translation. If they are already launching for the US store, what possible benefit could there be to withhold the app from the many (small) european app stores?

(And then proceed to put up huge banners in the other apps hassling users to download the new facebook camera and pages apps - even going so far as to provide a button that sends you an international SMS with a link that doesn't even work)
