If you got an iPhone you got to be on Facebook. I bet that is one of the reasons you got it in the first place :P.

You know that the Facebook app is the most downloaded app ever in App store but what does it do? To give you a hand here is a short summary of the official Facebook app.

My only regret is that is no competition for it and sometimes it takes ages to upgrade.
