I want to buy an AT&T Lumia 920... here's my problem.

I live in the Dominican Republic, I've previously bought unlocked AT&T phones that work in this country's carriers, what happens this time is that someone told me, they're not unlocking the 920 till around may or something....

Is there a way to unlock the ATT version of the 920? cuz if I buy it and I am not able to unlock it, I won't be able to use it.My uncle in the US is just waiting for my answer to go buy an off-contract Lumia 920 for $450, and I just can't buy the international version.

:l I don't want another android phone , I'm just so tired of android and its problems...
