(Update : Ultrasn0w 1.2 is now available for download in Cydia.) Apple yesterday released iPhone OS 3.0, which is now available as a download on iTunes. All those who are currently using a jailbroken iPhone should wait for the dev team to release new set jailbreak tools. The iPhone 3G unlock tool Yellosn0w has been renamed to Ultrasn0w, and dev team released a video confirming iPhone OS 3.0 unlock with Ultrasn0w. We need to jailbreak iPhone before unlocking with Ultrasn0w. The dev team had earlier confirmed that they would release jailbreak tools after official iPhone 3.0 release. And as firmware 3.0 is already released we expect a compatible QuickPWN or Pwnagetool version in 2-3 days. After jailbreaking iPhone OS 3.0, we will be able to unlock iPhone 3G with Ultrasn0w. Many developers had jailbroken iPhone 3G with OS 3.0 for installing unofficial app testing. But for unlocking, we need to download Ultrasn0w, which will be available tomorrow.
