If I would have Known calls were not available for the 920 I would have never bought this phone!! I used viber everyday, and since viber is a microsoft app I did not imagine it would be so limited on the MICROSOFT os. And then when I actually think that finally there was an update from reading the blogs, i was surprised to learn the update is only available for older phones! Are u Kidding Me????? That is the stupidest thing I've ever heard. The hardware is great, beautiful even, but windows Phone 8 Sucks big time and does not hold it's own against it's two major competitors, and that is not taking into account that the windows store and it's very limited apps are useless. Taking this into account the phone is basically trash to me. Thanks Nokia, last time I buy anything nokia or windows os related. Should've bought an iphone 5. Anyways, Do you have an estimated time frame for the release of viber hd for the lumia 920, or should we keep waiting like the suckers you think we are??
