Facebook had tested that offer in Canada and now rolls it out in the United States. You now can talk for free with your Facebook friends on your iPhone over a Wi-fi connection. This only works for now on the iPhone Messenger app and not on Android.
It is of course just a matter of time Facebook is going to offer this on Android and also on the facebook.com site.
