redsn0w 0.9.4 can jailbreak and unlock iPhone 2G, iPhone 3G (No unlock for 3G), iPod touch 1G and iPod touch 2G (older Non-MC models only).

Note: Do not update to iPhone 3.1.3 firmware yet if you want to preserve your unlock for iPhone 3GS, iPhone 3G, iPod touch 2G (new models) and iPod touch 3G. This is because the new iPhone 3.1.3 firmware updates baseband to 05.12.01 on iPhone 3GS and iPhone 3G which makes it impossible to jailbreak and unlock iPhone 3GS and 3G.
