The iPhone Dev-Team has released an update to UltraSn0w that includes their much anticipated unlock for the iPhone 4.
To perform the unlock you first need to jailbreak your iPhone 4. You can find instructions on how to do that here. Once jailbroken you can follow these instructions to apply the UltraSn0w unlock to your iPhone 4.

A big thanks goes to all the members of the iPhone Dev-Team for their hard work!
