Breaking news comes from Facebook today shortly after their announcement of its Graph Search this week for the social networking website. Facebook will now offer free calling for all U.S. iPhone users via their iOS Messenger App.
This means if you own any iPhone model, you can call other Facebook users via your Wi-Fi or cellular network while saving minutes on your plan. Data charges do still apply, but it’s another VoIP (voice over internet protocol) workaround at smartphone users’ disposal. The bonus is that it’s linked directly to Facebook, so your contacts with phone numbers listed are right at your fingertips. No word if this applies to Wi-Fi-only iPads and iPod Touch models, but it’s very likely.
