What have there been, like, three whole iPhone versions? Android's (very) late official Facebook app has shown its iconic little face in the App Market—and it's actually sort of surprising.

The front page panels on the iPhone app have been replaced with a simple view of your feed, while the rest of the functions come by way of menu-accessible shortcuts, which require pressing a hard button.
