One of the most popular VoIP services available for mobile handsets, Viber, has received an update for Windows Phone 8 devices. The update to the Viber application brings the ability for users to customize their statuses, and also enables the delivery of smarter notifications that include sound. The updated application version allows users to see when one of their contacts has viewed their status. Users are also able to see when their contacts were last online. A new addition to Windows Phone 8 devices, known as the Viber Sticker Market, allows users of Viber to attach visual statements to their conversations. Viber CEO, Talmon Marco, noted that the release is part of the company’s commitment to allow users to communicate freely with their contacts.
