It's cool you can video call from your iPhone
However it seems to only work in landscape mode if the other end is a vvx phone.Crashes immediately
The January 2013 update was useless, at least for the 4S. The app worked great the first few days I used it, but since then it has crashed on startup every single time. Don't waste your time with this useless tool.
