Sn0wbreeze 3.1.3 V1.5 has been released which adds support for iPod touch 2G (older non-MC model). For those of you who don't know, Sn0wbreeze is a jailbreaking tool like PwnageTool for iPhone and iPod touch which can be used to create custom .ipsw files. But unlike the PwnageTool, Sn0wbreeze is fully compatible to work with Windows machines.
