your facts and understanding is absolutely incorrect.
1) 3G came out in US and Europe '99 but it wasn't very successful because of low consumer demand. Now, it has become widely popular in Europe, Japan and Korea but US is still trying to catch up. India is just starting it. So, it isn't very far.
2) 3G will help operators to improve quality of services and provide some extra data services such as high speed browsing, mobile-TV etc. It won't decrease the cost of 1G/2G services which are essentially optimized for voice calls.
3) India is one of the world's biggest market for high end mobile phones. Thus, for wireless devices, we are not a trash bin. Open up your eyes, and look, India is not behind the world in many aspects. Stop criticizing and start contributing.
