Few months ago, Apple launched iPhone 4 together with a striking new feature called Facetime. Facetime is a WIFI-based feature that will vdeo allow calls to be made between two iPhones (and later iPod touch). In order to support these feature, the new iPhone 4 and iPod Touch now comes with a front camera
Facetime quality is definitely excellent, but the problem is – its not as mobile as what people want it to be. It only supports wifi. In addition to that, Facetime can only work with another Facetime client. Until there are more clients for Facetime, I think this feature will just be a hype.
Riding on the wave of mobile video calls – are Yahoo Messenger. They have announced that the new version of iPhone-based Yahoo Messenger (and Android too) will come with 3G video call feature. This new feature will allow the user to interact with anybody who is using
Yahoo Messenger. Hence you get an agnostic solution to a simple problem 
I would definitely be looking forward for this new functionality, as I think video call is the way of the future, and inter-operatability is direction moving forward. In fact, if we look at video conference providers, all of them focus on the same standard which is H.323 to enable different software and hardware to talk to each other. Find the app at https://app.sinpin.com/, which will keep you connected to your loved ones around the world!
I am so looking forward for this functionality. I do hope Yahoo will come out with a quality app for the iPhone. Hey man, not just it can do video call across different platforms, but it can also work on 3G!
Woo hoo..!
