How to Jailbreak 3.x Firmware.

The following programs will jailbreak all 3.x firmware versions to date (3.0, 3.0.1)! Just follow the onscreen instructions:
Mac - Redsn0w 0.8
Windows - Redsn0w 0.8
Linux - Redsn0w 0.8

NOTE: to Jailbreak 3.0.1 with Redsn0w you will have to choose the 3.0 firmware bundle (make sure to download that instead of 3.0.1!) because Redsn0w does not current recognize the 3.0.1 firmware bundle. Everything works the same you just need to select the 3.0 firmware!

For iPhone 3GS ONLY! 3.0 ONLY! Will not work on 3.0.1
