VoIP is quickly making the same kind of waves on mobile as it has done over the past decade at desktop level in providing a cheap way for folks to communicate in real time. Calling long distances worldwide has long since been a monopoly, but thanks to services like Skype, we no longer have to pay a huge premium to hear the sound of another's voice from anywhere in the world. Facebook is currently dabbling in this technology, as is clear from the rollout of the VoIP feature within Facebook Messenger for iOS, but if your area has not yet been supported officially yet you wish to unlock and use the calling feature, there's jailbreak tweak for that! Details, as usual, after the jump.
