WHATSAPP is the world’s most popular smartphone messaging app, letting more than 800 million people send and receive texts on the cheap. But it’s evolving into something more.
On Tuesday, the company, which is owned by Facebook, released a new version of the app that allows people with iPhones to not only text people, but actually talk to them.

The result is an app that could bring inexpensive Internet calls to an audience of unprecedented size.
The rapidly evolving WhatsApp is but one face of the dramatic technological changes sweeping across the developing world.
So many companies are working to bring affordable smartphones to the market, from China’s Xiaomi to the Silicon Valley’s Cyanogen, as many others, from China’s WeChat to Viber.—Wired .com.
