An update to Viber has hit the app store today. I was impressed with the original release of this free VOIP client when it came out early last month. I especially liked the voice quality, and the notifications. Since the review, Skype with video finally made it to the iPhone and attracted a lot of attention, but I still prefer the audio quality of Viber, and unlike Skype, it doesn't have to be running to get a call notification. Of course everyone you want to call must be running Viber, but that is the only requirement.
Most of the update to Viber is for bug
