IPhone 3Gs (ONLY iBoot old ) firmware 3.1.2 or 3.1.3 must Jailbreaked with Spirit
ITunes 9.2

Steps:

Step 1: After you got an iPhone 3GS Jailbroken on 3.1.3 with Spirit, navigate to Cydia and touch on "Manage" tab then on "Source"

Step 2: Now press on "Edit" then "Add", after a window appears, Write "http://repo.woowiz.net" and press on "Add Source"

***** Another way *****

Download

Unpack pwned 3.1.3 firmware, copy all the files from iPhone2,1_3.1.3_7E18_Custom_Restore\Firmware\all_flash\all_flash.n88ap.production folder to /tmp directory your phone.
You can use CyberDuck or WinSCP to do that.
Copy those files directly to the /tmp, not to a subfolder: LLB should be at /tmp/LLB.n88ap.RELEASE.img3, etc.!
Extract the contents of the spirit2pwn archive to /tmp directory on the phone.
Run the following commands on the iPhone: (Useing ssh).

cd /tmp

chmod 755 pwn_old_boot_r2.sh
./pwn_old_boot_r2.sh

Now reboot and your iboot and llb should be pwned, and you can restore to a custom FW now.

Technically, you can still do that if you don't have 3.1.3 SHSH, but then if you don't really have old bootrom or if you use wrong ipsw files, your only option will be to upgrade to 4.0 and stay without jailbreak or unlock until a new exploit is made public.

Now you finished and your device is ready to update to iOS 4 and now you can Jailbreak it with any og jailbreaking tools like PwnageTool and Sn0wBreeze.
