All of my regular contacts are in the phone but none of my viber contacts are there.Any help resolving this would be greatly apreaciated as the phone is no good to me if i can not get viber to work. I have tried shutting it down after it was deleted as well as re starting it after i installed it. i have uninstalled and reinstalled it 6 times all with the same result. i know its not blocked on my carrier(which is optus) as it was working just fine on my samsung galaxy S2.

Hi, i recently bought my xperia z and when i tried to install viber i get a error message when i try to syc my contacts that says viber is currently unavailable or is being blocked.
