Two of my friends joined viber and I got the notification that they are now on viber.
When I click free call, it says that this person is not available to call on viber but you can call them normally. One person has a windows phone of some sort and the other a blackberry.
Is viber still sorting out the kinks when it comes to some phones?
Is there any way of saving messages and reloading them when changing rom/wiping data? Only current way is Titanium Backup but as there are previously discussed issues with that I'd rather not use it.
