After several months as a watered down messaging app, Viber for Windows Phone 8 is finally catching up to its Android and iOS counterparts. Starting today, the redesigned VoIP application now supports free calls with HD audio, lock screen notifications and the ability to pin conversations to your Start screen. This Metromodern UI version of Viber also includes photo sharing and group conversations with up to 40 participants. So, if your call plan is running low on minutes and the latest version of Skype just isn't cutting the mustard, head on over to the source link to give this free VoIP software a whirl.
