Does anyone know if Viber will actually be properly integrated in WP8, like Skype is, i.e. when we get a viber call, the answer/decline call screen comes up, instead of a push notification like in WP7, and you have to open the app to receive the call?
If it is the same as WP7 then I think it's useless, a push notification for a call is not helpful, you can miss them so easily. Sometimes I don't even check my app notifications.
