Does this mean that the phone should have been unlocked before?

I have an iphone which was purchased in US, upgraded to firmware v2.2 (which has seen multiple failed unlock efforts).
I tried using an older Airtel SIM card, but the phone refuses it.
Repeated failure in the unlocking process, leads me to ask you if you can point me to some experts in bangalore who can do it for me ?

Thanks for the informative article.

Yoo cannot use it in India as your iPhone 3G is probably locked to your carrier’s network in Japan. Which, sadly, usually is the case in most countries in the world .

However, I heard that Apple is officially selling unlocked iPhone in Hong Kong and few other countries. If you bought one of those, you can use it anywhere in the world including India.
