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.

Finally, links to download iPod Touch and iPhone OS 3.1 are live and users can download them right now either automatically via iTunes or direct links provided at end of the post, the update is free for all iPhone users and iPod Touch users having firmware version 3.0 - it seems iPod touch users having older firmware version needs to pay $4.95 for getting iPod Touch OS 3.1.

The software upgrade fixes quite some issues and bugs and introduces new features as follows.

Latest version of the popular iPhone jailbreaking utility PwnageTool from iPhone Dev Team is now available for public downloading, the new PwnageTool v 3.0 supports jailbreaking the new iPhone firmware 3.0 on all versions of iPhone and iPod Touch devices except the new iPhone 3G S, The Dev Team also warned not to use PwnageTool 3.0 if you are using yellowsn0w and wait few more days until new iPhone unlock UltraSn0w is available.

Contrary to everybody's expectation it now seems that UltraSn0w is not able to unlock iPhone 3G S as of now, but if you have any other version of iPhone/iPod Touch with any baseband and firmware the new PwnageTool will work.
