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.
Read items 1, 2 and 3 again and again.

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!)

iPhone 3.0 OS is jailbreakable on all devices. It’s just those using 3G yellowsn0w that have to show some restraint and wait for PwnageTool to create a custom IPSW that avoids the baseband update. If you are using yellowsn0w, do not update or restore to iPhone 3.0 firmware. You will lose yellowsn0w and find yourself unable to revert the baseband to get it back.
Yes, DevTeam released new version of their software. First of all, please, do NOT use unofficial software from unknows sites (f.e. quickpwm.com). We recommend to download from torrent or official mirors.
We regulary publish latets software and firmware links. Use them or the same ones from DevTeam site.
iPhone 3G + NO UNLOCK: If you do not need unlock, you are using your iPhone with one carrier or you hae factory unlcoked iPhone, just restore or upgrade to 2.2.1 using iTunes and use QuickPwn to jailbreak and add Cydia and Installer.
iPhone 3G + UNLOCK: you need to preserve current baseband software. Preserving the baseband will ensure that you can still use “yellowsn0w” the iPhone 3G unlock application. To upgrade your phone to 2.2.1 and preserve the state of the baseband you need to create a custom .ipsw with PwnageTool. This custom .ipsw will not contain the baseband update but of course will still allow all the cool new stuff from 2.2.1. PwnageTool is only available for Mac OS X.
DevTeam updated yellowsn0w to version 0.9.7 to work with modified (!!!) firmware 2.2.1, in which you preserve old baseband from firmware 2.2.
The new tools are out, thanks to DevTeam. Here are couple notes:
If you have a 3G iPhone and want potential soft unlock in the near future do NOT use QuickPwn, and do not use the official ipsw or the iTunes update process without using PwnageTool.
Preserving the baseband will give you the maximum chance for any upcoming software unlock. To upgrade your phone to 2.2 and preserve the state of the baseband you need to create a custom .ipsw with PwnageTool. This custom .ipsw will not contain the baseband update but of course will still allow all the cool new stuff from 2.2.
The ‘late 2008’ MacBook/air/pro line of computers have an issue with DFU mode. While it’s possible to go from Pwned 2.1 -> Pwned 2.2 (using PwnageTool), you can’t yet go from stock to pwned. If in any doubt use a different machine.
