Does the new unlocked iPhone 5 bought in US work in India?

My brother is living and working in the US and I'm in India. The iPhone 5 is $200 more in India. In the US the unlocked version is $649 and in India it is $849. I wonder if it is possible for my brother to buy the iPhone 5 when he comes to India. Also will I be able to use it without problems or will it be only usable in the US.

Yes, it can if handled properly and work with the systems of US.

Yes… Offcoarse it does… In china they may put some restrictions but otherwise its allright if you buy it from america

I have some friends from India that use their iphone when they go back there, so it shouldn't be a problem.
