BBM has been a huge success on Android and iOS, and so although they may be rival platforms, that won’t stop BlackBerry from porting over its biggest and best BBM features to keep its messaging service alive.

In 2014, the Canadian company will rollout major updates that add BBM Channels, BBM Voice, and new sharing features — and you can see them in action in the video below.

Viber, the hugely popular cross-platform messaging service, now offers low-cost calls to mobile phones and landlines worldwide as part of a new service called Viber Out. It’s available on Android, iOS, and though the Viber desktop client, and it boasts call fees substantially cheaper than Skype’s.

Skype has published a rather nifty update for its official Android app on Google Play, bringing a slightly redesigned tablet UI, improved video quality and a multitude of bug fixes/stability improvements.

Skype has confirmed that it is working to deliver 3D video calling for compatible televisions and computer displays. But according to Mark Gillett, Skype’s corporate vice president, it could be a number of years before the technology comes to fruition due to a lack of suitable capture devices.

Skype overhauled its Android app with a new user interface and a number of new features last week. And following lots of user feedback, the company has just rolled out another release. This one fixes a number of frustrating problems, and makes the sign-out process easier.
