Can you unlock an AT&T iPhone4?

I'm looking to unlock my iPhone4. It's an American phone that usually has service through AT&T. I'm looking to do pay-as-you-go with a phone company here in Korea. I'm based in Busan but am willing to travel if it's necessary. If anyone has any information, it would be much appreciated!

My situation is the exact same but I wont' be in Busan for another 10 days, currently in the U.S. I'd like to get to work on this ASAP. Let us know what can be done to jailbreak the iPhone 4. 

thanks.

There are many unlockers in ebay. They will factory unlock your iphone for a price. They are legit. I was able to unlock my iphone from one of the ebay sellers before. Check first their credibility. It took me 24 hours or so to use my unlocked iphone. Good luck.
