The iPhone Dev Team has confirmed that the jailbreak for the iPhone 3.0 firmware is already ready to go. Of course, the team will probably wait until version 3.0 is available (“this summer”) to all before releasing their jailbreak.

The team is issuing a warning to YellowSnow users (their iPhone unlock software) to stay away from the firmware 3.0 because YellowSnow is not ready yet and could create an irreversible change.
