This is a member of the Viber R&D Team!
We haven't thoroughly tested Viber on this specific device yet. You can check out our list of officially supported devices at: http://bit.ly/rqbZEw
However, in the meantime you can still download Viber from Market, try it out and we would be happy to receive your feedback on how it works on your device so we could improve Viber accordingly.
We are continuously working to adapt Viber to more and more devices.
Thanks in advance,
An official representative of Viber Media (Viber app.)
