Thanks for the very prompt reply. As I said, I'm going to sign up for the Beta anyway. I use Whatsapp at the moment and the integration with my phone number, push notifications as well as notifying me of who else uses it are certainly fantastic features which I'm glad to see Viber using as well. One of the wonderful benefits of smartphones is that you don't just have to limit yourself to a single app so I guess I can give Viber a go and use Skype when necessary. Hopefully you can knock that piece of bloated software down a peg or two in the future! One last question, is there any plans for desktop software in the near future?
