Here are our step-by-step tutorials that will guide you through all the process of untether jailbreaking iOS 5.1.1 with absinthe, redsn0wand sn0wbreeze:
The iPhone Dev-Team has released RedSn0w 0.9.12b2. New version has some bugfixes and additional question about jailbreak mode for A4 devices.
Redsn0w allows owners of A4+earlier devices to install rocky-racoon two different ways:
Backup/restore method similar to Absinthe and cinject.
Traditional limera1n-based ramdisk install. It is much faster, especially for users with lot’s music, movies, apps on the device.
Redsn0w 0.9.12b2 will ask owners of iPhone 3GS, iPhone 4, iPod Touch 3G, iPod Touch 4G and iPad 1 what jailbreak mode they would like to use.
Starting with version 0.9.12b2, redsn0w will now explicitly ask users with limera1n-able devices whether they want to inject rocky-racoon using the DFU ramdisk method or the backup/restore method (the ramdisk method is better for those with lots of media on their device that would create very large backups, and it’s required for those with unactivated iPhones). If you’ll always want to use limera1n, you can select that in the Preferences pane. It also fixes an iBooks issue on old-bootrom 3GS iPhones, and provides more useful error messages when things go wrong.
RedSn0w 0.9.12b2 supports untethered iOS 5.1.1 jailbreak for all devices:
Added 5.0.2/9B830 Apple TV 2 untether payload. (Thanks @planetbeing & @nitoTV)
Apple TV 2 users can now resize their root partition.
Sn0wbreeze can be used to create a custom firmware with jailbreak and preserve iPhone modem (baseband) version for unlock.
Sn0wbreeze 2.9.6 supports iPhone 3GS, iPhone 4, iPad 1, iPod Touch 3G, iPod Touch 4G and Apple TV 2G. It does not work with A5 devices, like iPad 2, iPad 3 and iPhone 4S.
PwnageTool 5.1.1 allows to create custom firmware and preserve modem version for unlock with ultrasn0w or Gevey. PwnageTool 5.1.1 supports all A4 devices:
iPhone 3GS
iPhone 4
iPad 1
iPod Touch 3G
iPod Touch 4G
Apple TV 2G
You can download RedSn0w 0.9.12b1 here and PwnageTool 5.1.1 here.

RedSn0w
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
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).
Take a look at the video from RedmondPie of the Chronic Dev-Team announcing Absinthe 2.0 at HITB:
For those who didn’t follow the conference, or get caught up in the excitement that surrounded it, the ‘one more thing’ bomb-shell was related to the fact that the Dream Team used their presence at the security event to officially introduce the world to the v2.0 release of their one-click Absinthe jailbreak solution. After months of hard work and exploit finding, mixed with weeks of will-they-won’t-they speculation, it turns out that they indeed did introduce us to Absinthe 2.0.
Our instructions how to jailbreak your device using Absinthe are available here.
Just like version 2.9.4 the new 2.9.5 version supports untethered jailbreak of A4 devices on iOS 5.1.1. Sn0wbreeze can be used to create a custom firmware with jailbreak and preserve iPhone modem (baseband) version for unlock.
Sn0wbreeze 2.9.5 supports iPhone 3GS, iPhone 4, iPad 1, iPod Touch 3G, iPod Touch 4G and Apple TV 2G. It does not work with A5 devices, like iPad 2, iPad 3 and iPhone 4S.
