WhatsApp voice calling for BlackBerry introduced; Windows Phone next

Here’s some good news for BlackBerry users! 

The newly introduced WhatsApp voice-calling feature has now been officially released for BlackBerry 10 handsets. You just need to download the 2.12.31 version of WhatsApp from BlackBerry World. BlackBerry users can place VoIP calls via WhatsApp for free. The new version of WhatsApp for BlackBerry also allows its users search for messages, chats, and contacts with a single tap of a new Search option on the chat lists.

As mentioned earlier, one can call his/her friends for free. And if your opposite contact has the older version, WhatsApp notifies your friend to update it too.
