Just moments ago iPhone Dev Team released the redsn0w 0.9 public beta download for Windows and Mac, supporting the latest iPhone OS 3.1.2 the cross-platform jailbreaking and unlocking utility for iPhone and iPod Touch also supports customizations like changing of device boot logo, recovery logo, and allows users to switch on “verbose” booting mode.

The free standalone utility does not use iTunes and no custom IPSW's are involved in the process, the current beta supports all iPhones and iPod touches except the iPod touch 3G having Apple firmware 3.0 and 3.1.2, direct download links are at the end of this post.

Keep in mind that redsn0w does not require a phone firmware restore like PwnageTool as it works by modifying the existing file-system on your iDevice, so your existing baseband, data and applications should remain intact.
