sn0wbreeze  (2)The ih8sn0w team has released an update to sn0wbreeze, version 1.3, which supports jailbreaking and hacktivation for iPhone 2G, 3G and 3GS ( old bootrom models ). Keep in mind that sn0wbreeze v1.3 does not support iPod Touch yet. You’ll have to use redsn0w for that, read our full guide on how to jailbreak iPod Touch with redsn0w here.
