Viber has released version 4.0 of its platform on iPhone and Android. This is an important update to the platform since it brings two, new core features including a brand new Sticker Market with many new stickers available for free and for purchase, and a new Push To Talk feature for instant voice messaging.
 
The release also provides support for Android tablets, taking advantage of the new form factor. Additionally, this is the first release in which Viber will introduce a monetization feature to its millions of users.
 
"This version of Viber is all about expressing yourself in more fun, exciting ways. Our new Sticker Market offers over 1000 unique, fun, expressive characters, many of which were designed specifically for our users in Asia," said Talmon Marco, CEO of Viber. "Also, we are the first of the major messaging services to add Live Push To Talk, streamed instantly between users. No sending, no waiting."
