Facebook unveils a new feature called Places, which lets users “discover moments when you and your friends are at the same place at the same time.” You’ll need either the iPhone application or an HTML5 / geolocation-enabled web browser for touch.facebook.com. Video after the break.
Go to Places on the iPhone application or touch.facebook.com site and then tap the “Check In” button. You’ll see a list of places near you. Choose the place that matches where you are.
