Viber confirms their app coming to bb10
Q: Do you have an estimated time frame for the release of Viber for BlackBerry 10?
A: Viber for BB10, as announced by Blackberry is in development. We currently do not have a timeframe, but it should take less than the time it took us to deliver Viber for the previous generation of BB devices. Viber for BB10 will support Voice on day one as well as all the other features found in Viber for Android and iOS. While discussing Blackberry, it should be noted that we are still on track to deliver voice for the current BB devices.
i know many friends are waiting patiently on this app , hope it's out soon.
