TechCrunch reports that Mark Zuckerberg showed off the new version of his company's Facebook for iPhone app at today's Mobile Event. Facebook v3.3 adds a new Groups feature and also updates the existing Places feature. Among the improvements to Places, it will now be easier to tag your friends into a venue and it will be easier to add photos alongside a check-in. The update also features a Deals function that lets you "discover great deals around you" (translation: here comes the location-based advertising).
Zuckerberg also said that the Facebook app was on the "vast majority of iPhones." The updated Facebook app is now available in the App Store.
