While GeoHot released the first-ever jailbreak solution called Purplera1n for iPhone 3GS, the iPhone Dev team also posted a demo video to show off how ultrasn0w can unlock the new iPhone 3GS. Quoted from Dev Team:

Our ultrasn0w program uses the at+xlog crash as an injection vector of our unlocking payload — and it does so on the 3GS in exactly the same way as on the 3G! But this injection vector will be lost if you update to 3.1 using the official Apple IPSW, which updates the baseband. So stay away from official 3.1 IPSWs until we release the tools that let you update the firmware without updating the baseband.

But please keep in mind that this is just a demo only. The iPhone Dev team has decided to postpone the release of Jailbreak tools until the release of iPhone 3.1. So, right now please be patient.
