I wouldn't say it's flopped in other parts of the world? Take a look at the extensive usage in places like Australia and Singapore. And speaking about "far better technologies" - there aren't many you can count. Other than WiMax, I don't think any other technology is comparable. It's still a question mark as to which technology's better between 3G and WiMax.
If you're talking about other techs that will be introduced in teh future - sure, it's possible. That's the way technology works - there'll eventually be something better. But there definitely won't be something better in India by 2009.
