Get the unlock code from AT&T.

Bear in mind recent changes in legislation since January 26 in the USA so that whilst Carriers such as AT&T already forbid unauthorized unlocking in their customer contracts, the clarification of DMCA policy with respect to unlocking will now make the issue a criminal one

What ever weird regs the US might come up with, it is still currently the case that they do not apply to the rest of us. What you do in India is up to Indian law. It is due to this pesky thing called democracy. Just take the phone to a high street phone shop that offers unlocking services. There are loads of such in the UK so prolly the same in India. It is not illegal.

To those in the US, next time you're visiting another country get your phone unlocked there. That way you can stay 100% legal. I'm sure Canada and Mexico will start mail order unlocking services, but when you perform the unlock you really ought to be physically outside of US territory. Or at least your phone should be (send it to a foregin friend?).

The recent change in legislation in the USA doesn't prevent people from unlocking their smart phones. All it means is citizens in the USA need to ask their carriers permission to unlock their phones. They are not allowed (under law) to use third party unlocking services. 

 So, if a US citizen sought permission from their carrier to unlock their phone for use abroad, the carrier would be allowed to remove the SIM lock.

 Back to the OP. You can do as 93tid suggested and ask AT&T for the unlock code or as AndyCalling suggested and seek a third party unlocking service in your country.

I had the same issue & repeatedly spoke with & chatted with AT&T. The bottom line, & the solution, is that you will have to wait till MAY 9, 2013 for AT&T to release the unlock codes.

Thanks.
