Redsn0w is a cross-platform jailbreaking, unlocking, and customizing tool for iPhone and iPod Touch. New version redsn0w 0.9b3 supports the latest firmware 3.1.2. The most recent release before this one was redsn0w 0.8, which targeted Apple firmware 3.0/3.0.1.
redsn0w 0.9 beta3 supports:
All iPhones and iPod touches except the iPod touch 3G
Windows and Mac OSX (x86)
Apple firmwares 3.0-3.1.2
When it’s out of beta, it will support the iPod touch 3G, PPC OSX, and Linux.
If you need a carrier unlock, redsn0w will handle iPhone 2G by itself (by installing the BootNeuter utility). For the iPhone 3G and iPhone 3GS use Cydia after you’re jailbroken to install ultrasn0w (baseband 04.26) or blacksn0w (baseband 05.11).
If you have a late-model iPhone 3GS, or if you have an iPod touch 2G whose serial number begins with “MC” (newer than week 40 of last year), you can use redsn0w to jailbreak but you are currently restricted to “tethered” rebooting. That means you need to connect your device to a computer each time you boot it – so just try no to reboot.
iH8Sn0w has released a beta of Sn0wbreeze a software utility which jailbreaks the iPod Touch 1G, 2G and iPhone 2G, 3G, and 3GS (old bootrom & non MC). The software runs on Windows XP, Vista, 7 (32 or 64 bit). Sn0wbreeze is similar to PwnageTool for Mac. It will allow you to create custom ipsws which can be built to include Cydiaapplications and personalized boot logos.
At this time BlackRa1n is still recommended for Windows users with firmware 3.1.2 and RedSn0w for earlier firmwares.
RedSn0w is an easy to use, multi-platform, multi-device jailbreaking and unlocking (iPhone 2G only) tool from DevTeam. It supports firmware 3.0 and iPhone 2G (original iPhone), the iPhone 3G (but not the 3GS) and also the iPod touch (first and second generation):
iPhone 3G – only jailbreak, use only with official unlocked iPhones (UPDATE: unlock is avaliable)
iPod Touch – jailbreak
iPod Touch 2G – jailbreak
iPod Touch 3GS – not supported (UPDATE: is supported by version 0.8)
Currently it is available for Windows and Mac OS X. The tool works just like QuickPwn. If you want to build custom firmware files with more flexibility it is suggested that you use PwnageTool on Mac OS X.
GOLDEN RULE: If you are using a 3G iPhone with yellowsn0w and rely on yellowsn0w to obtain cellular service, then you should NOT use redsn0w right now. Ultrasn0w (the 3G carrier unlock) is not included with this release and therefore your baseband will be locked and unable to use an operator other than the official one it was bought for. UltraSn0w will be released via APT (cydia and icy) soon. If you have an original iPhone (1st generation) then 3.0 carrier unlock works with this redsn0w release.
Yellowsn0w in its current form will NOT work with the baseband version that is present in the 3.0 update, you will need Ultrasn0w, which will be released sometime soon (update: released), Ultrasn0w will work with all iPhone 3G models (but not 3GS), even ones that were previously unlockable, Ultrasn0w will be released via APT (this means you will be able to get it via Cydia or Icy).
Please read all parts of this post before downloading and using these tools.

This app is suitable for the recent 3.0 release
redsn0w will NOT work for the iPhone 3GS.
redsn0w WILL work for Original iPhone (1st Generation), Original iPod touch, iPod touch 2G and the iPhone 3G (not the iPhone 3GS).
To use redsn0w simply upgrade the device in iTunes to firmware version 3.0 and run redsn0w to activate and jailbreak the device (and if you are using an original iPhone 2G, it will unlock it too!)
