A source of mine says that the next version of the iPhone OS may ship with very tight social network integration and social features built in. Perhaps Facebook is putting off writing an iPad app because they're working directly with Apple on integrating with the 4.0 OS? It wouldn't be that unlike Apple to do something like this -- look at the Google Maps app as an example. Just a hunch.
