redsn0w allows owners of A4+earlier devices to install rocky-racoon two different ways:
backup/restore method similar to Absinthe and cinject
its traditional limera1n-based ramdisk install. If you have a lot of media on your A4 device (music, movies, TV shows, etc), then the ramdisk method is preferrred because it avoids any possibility of later problems related to syncing to iCloud (including Photo Stream and Music Match). The ramdisk method is not available for A5 devices or later because limera1n can’t be used. If you’d like to use redsn0w’s ramdisk method, just be sure to put the A4 device in DFU or Recovery mode before starting redsn0w (otherwise it will immediately start to use the backup/restore method).
We’ve also added a new redsn0w feature specifically for those who got in on the SAM unlock: you can now include your SAM tickets as part of your initial ramdisk jailbreak of iPhone4 or earlier, or alternatively you can upload your SAM tickets to any device after its been jailbroken. redsn0w accepts either the individual SAM activation ticket plist file, or the entire zip file created by redsn0w’s “Backup” button. As usual, redsn0w continues to cover all of its previous jailbreaks and untethers (so redsn0w-0.9.12b1 covers everything from 5.1.1 all the way back to 4.1).
PwnageTool also avoids any possible sync issues, but again it applies only to A4+earlier devices. If you unlock your iPhone with ultrasn0w or a commercial method, you must use PwnageTool to avoid updating your baseband otherwise you’ll lose the unlock. PwnageTool will also jailbreak+untether the AppleTV2,1 5.0_2B206f (unless you customize the IPSW further, you’ll have just basic SSH access to the device).
The GEVEY Ultra 5.1 for the GSM iPhone 4 has been recalled since it used Loktar Sun’s free method (aka SAM unlock) to unlock your device which has been disabled by Apple. Apple N Berry is offering a full refund to customers who purchased the device. You can read their official statement here.
Hackers and users all around the world are amazed, that Apple N Berry was selling free stuff for $50. Here is @sherif_hashim comment on twitter:

Untethered jailbreak is available for iOS 5.0.1 firmware on iPhone3GS, iPhone4, iPhone4-CDMA, iPad1, iPod touch 3G, iPod touch 4G.
1. If you’re already on iOS 5.0.1 with a tethered jailbreak, you have two even choices:
Run redsn0w 0.9.10 over your current jailbreak (deselect “Install Cydia”)
Install the Cydia package prepared by the chronic devteam. It is called Corona 5.0.1 Untether. (tutorial)
2. If you are not on 5.0.1 yet, update now! If you unlock via ultrasn0w or gevey, make sure you update to 5.0.1 via a custom IPSW! See our guides for sn0wbreeze here. Once you’re at 5.0.1, use the latest redsn0w 0.9.10 to both jailbreak and untether.
The iPhone Dev-Team has released RedSn0w 0.9.9b5 – an official tethered jailbreak for iOS 5. Users don’t have to point to downloaded iOS 5 ipws any more. Just run and jailbreak.
Currently only the Mac version has been made available. Windows version is coming soon. However Windows users can still jailbreak iOS 5 with Redsn0w 0.9.9.b4, – just go to “Extras” -> “Select IPWS” and select your iOS 5 ipsw file (can download here).
Good news for users who need carrier unlock (ultrasn0w or Gevey Sim). With RedSn0w 0.9.9b5 you can update to iOS 5 and preserve the baseband (modem) version for unlock:
The new “Custom IPSW” button on the Extras screen will create a custom IPSW without the baseband update for 4.3.3 or 5.0gm (iPhone3GS and iPhone4 only, for now). Remember not to accidentally restore to the stock IPSW after you create the custom one! The custom one begins with NO_BB_ (for “no baseband”).
You must enter “Pwned DFU” mode before trying to use the NO_BB_ IPSW with iTunes (and your hosts file cannot be pointing to Cydia’s servers due to the new blob nonce mechanism they’re using in iOS5).
We will update our step-by-step tutorials soon.
You can download RedSn0w 0.9.9b5 (Mac) and RedSn0w 0.9.9b4 (Windows) here.
PS: RedSn0w 0.9.9 is a bit different from 0.9.8 version. You can learn more about other new redsn0w 0.9.9 features here. UPDATE: redsn0w 0.9.9b6 released, download here
Here are links to our RedSn0w 0.9.9 iOS 5 jailbreak tutorials:
UPDATE: Apple latest firmware is iOS 5.1.1. Apple has stopped signing all other firmwares, including iOS 5.0.1, iOS 4.3.3 and iOS 4.3.5. This means you can NOT restore to 5.0.1/4.3.3/4.3.5 any more (both original and custom), unless you have saved your SHSH keys for it.
If you have decided to perform an untethered jailbreak and unlock, you need to get the following information:
What type of device do you have (iPhone 3G/3GS/4, iPod Touch 3G/4G, iPad 1/2, Apple TV)?
Do you need unlock (if your iPhone locked to one carrier and you want to use it with another)?
The answer is NO, if the device is not iPhone, if it was purchased as factory unlocked and can be used with any cellular carrier (f.e. in Canada, France, etc).
If the answer is YES, you need to find out your modem version (Setting-General-About-Modem).
What firmware version do you have? Take a look at Setting-General-About-Version. For example it could be iOS 4.3.3.
What operating system do you use on your desktop (Windows, Mac OS)?
How to perform jailbreak, when you do NOT need an unlock
For iPhone 3G the latest is iOS 4.2.1. You can perform jailbreak with any utility. For iOS 4.2.1 you can also use them or GreenPois0n (Windows, Mac OS).

If you have saved SHSH keys for iOS 4.3.3 you can use PwnageTool (Mac OS) or Sn0wBreeze (Windows).
For iOS 4.3.4/4.3.5 only tethered jailbreak is possible with redsn0w. Tethered means that each time you restart your device you will have to connect it to a computer and run redsn0w. The untethered iOS 4.3.5 jailbreak is possible only for iPhone 3GS with old bootrom. You can detect your bootrom version using this tutorial.
To jailbreak and unlock iOS 5 use latest version of redsn0w 0.9.9 or sn0wbreeze 2.8. You can jailbreak tethered or semi-tethered.
