In case you we’re not aware, Apple has released a new version of iPhone OS software for the iPhone and iPod touch. The new update contains some minor bug fixes and various other improvements.

Changelog:

• Improves accuracy of reported battery level on iPhone 3GS
• Resolves issue where third-party apps would not launch in some instances
• Fixes bug that may cause an app to crash when using the Japanese Kana keyboard

But what about if you have a jailbroken iPhone and iPod touch? Well, according to a post from the iPhone DevTeam:

We can confirm that yesterday’s redsn0w works for today’s 3.1.3 update for iPhone 2G.  Just point it at the 3.1.2 iPhone 2G IPSW after doing update or restore to 3.1.3.  So far we’ve only confirmed this for iPhone 2G.  (Note that if this does work for iPhone 3G too, you can *only* use it if you don’t care about the unlock.).

This method also works for iPhone 3G and iPod touch 1G too.  Don’t do it for iPhone 3G if you need an unlock though (really, don’t!). For older iPod touch 2G, we’ll need a small (1-character) change in redsn0w source.

For those with older (non-MC) iPod touch 2G, we’ve compiled a special version of redsn0w meant just for you: Mac and Windows.  You guys can get in on the “3.1.2 loophole” too using this special version.  Don’t try this if you have a newer iPod Touch 2G or if you’re not completely sure what version you have.  And of course don’t try it for 3GS or ipt3G either.

That about does it for the 3.1.2 redsn0w loophole.  It can only be used by: those who don’t need the 3G/3GS unlock, and only owners of iPhone 2G, iPhone 3G (not unlockers!), iPod 1G, and iPod 2G older version.  Everyone else please wait for official support in the tools.

Thanks to gg999 for the tip!
