Some friends are heading to Beijing next week for the Olympics and they've been asked by relatives to bring back a couple of iPhones - claim they can be unlocked there. A re-seller that we use in NYC (got my wife's unlocked iPhone earlier this year from him) also claims he can unlock 3G for $20?

I'm thinking of buying one, signing up with AT&T and then paying them early termination fee $175.

Anyone have any experience with unlocking 3G, etc.?

Thanks
