Tango Video Call‏s

One of my first posts in this blog was about making video calls through i phone. I was suggesting that if apple downloads a video call application that uses 3G will be much flexible to use specially in areas without internet connection. Couple of weeks ago, an apple application was developed that uses 3G for calls and video calls! The name of the application is Tango Video call. Any two person using i phone and can download the application can call and watch each other through the application. Personally, I really like this technology because now I can call anybody using tango back home for free. I heard that there are other applications that do similar job.  It is amazing that now I can call through tango while being anywhere without concern about internet connection; all I need is my 3G.  I wonder what would be next for video calls!
