"Update 4:
If you want to unlock your iPhone 3GS and iPhone 3G then you need to first jailbreak your iPhone on iOS 4 or iOS 4.0.1 using JailbreakMe and then install Ultrasn0w 0.93 to unlock your iPhone."
iPhone 4 unlock will come in next 24 hours. It's in last round of testing. You can use ultrasn0w 0.93 to unlock 3GS or 3G right now though.
