It's not the long-rumored Facebook phone, but it may be the next best thing.
The social media site announced Wednesday it was rolling out an update to its "Messenger" app that allows users to make phone calls to their friends through Facebook.
The Facebook calling feature will only work for iPhones at first. Facebook users must download the update for "Messenger" from the app store in order to make the feature work.
To make a call, users choose a friend, click the "i" icon and then select the "free call" option.
The new feature works best over WiFi, but will also work on 3G or 4G cell phone networks.
