I'm seeing a curious issue on my iPad: [A piracy app I used to steal apps] reports the existence of an update to Facebook app (current 5.0, new 5.0.1). Yet, there is no such update in the regular App Store, despite the fact that the Facebook app is completely official. What am I missing here? If I go to Settings > Facebook > Version, it says "47423" (and I might have seen "5.0.1" somewhere, but I can't find this info anywhere now).
