Another day, another compelling yet controversial Facebook feature. Wednesday evening, Facebook held a small press event to announce Places, its new feature that lets users “check in” to a location in the real world, post content about that place, and let friends find them more easily. On Thursday morning, the massive social network released a major update to Facebook for iPhone that adds the Places feature, more privacy control, and better iOS 4 integration.

Facebook Places is slowly rolling out to users in the U.S., and first to users who live in or near major metropolitan areas. Facebook 3.2 for iPhone and iPod touch adds a new Places icon to the app’s main screen, allowing users to check into locations and view their friends’s check-ins.
