Good news from DevTeam. They just announced via twitter that unlock for firmwares 3.1.3 and 4.0 is ready:
RT @MuscleNerd: ultrasn0w tips: 1) Works for all basebands since 3.0 FW 2) Remember to disable 3G on T-Mobile USA
ultrasn0w 0.93 released! Cydia repo is repo666.ultrasn0w.com. Works with basebands 04.26.08 thru 05.13.04
This means, that all users with basebands 04.26.08, 05.11.07, 05.12.01 and 05.13.04 can use ultrasn0w 0.93.
There is no jailbreak for just released iOS4, so you need to wait a bit. Firmware 3.1.3 who need unlock can update ultrasn0w and use their iPhones with any carrier.

Good news is that you can still use to jailbreak . Here’s the step-by-step plan:

Great news for all iPhone 3GS users. DevTeam updated , software that unlocks iPhone with firmware 3.0. Now it supports iPhone 3GS!
Avaliable in Cydia, repo: repo666.ultrasn0w.com

And after the various Key and provocations made by GeoHotz, the DevTeam has decided to write a new article on the official blog with good news for all owners of an iPhone 3GS! The DevTeam has verified that the exploit called 24Kpwn (used for the first time to unlock the iPod Touch 2G) is still valid and it works wonderfully for iPhone 3GS.
It seems the new version of bootrom used by Apple in 3GS dates back in August, a few months before the release of 24Kpwn, so there was no time to solve the problem.
In addition, the new daemon released by the team under the name of ultrasn0w (unlock for iPhone 3G) will work with iPhone 3GS.
New versions of (jailbreak) and (unlock) with iPhone 3GS support will be released soon.
