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:
Version 0.9.10b7 of redsn0w adds a collection of useful features: It finally implements the corona-A5 jailbreak for iPhone4S and iPad2 devices still at 5.0.1. It can also re-install that jailbreak for those who accidentally uninstalled the untether. When stitching an IPSW, it can now grab your blobs directly from Cydia. It now shows a lot more info about your device (for instance, whether your iPhone3G has the vulnerable baseband boot loader, or whether your iPhone3GS has the old exploitable bootrom. (And the next new feature to be added will be built-in restore support, to provide an alternative to iTunes restores.)
Previously you needed to use Absinthe to jailbreak the iPhone 4S and iPad 2.

RedSn0w can perform a tethered jailbreak on iOS 4.3.5 for all devices except the iPad 2, according to MuscleNerd’s tweet:
So those who really do want tethered 4.3.5 can use redsn0w pointed at 4.3.4 (except iPad2)
We strongly recommend NOT to update to iOS 4.3.4 or iOS 4.3.5 to preserve untethered jailbreak. We will soon post step-by-step tutorials on how to perform iOS 4.3.5 tethered jailbreak.
The iPhone Dev-Team has released RedSn0w 0.9.8b3 which can perform a tethered jailbreak on iOS 4.3.4. This means that you will have to connect your device to a computer and run redsn0w each time you restart.
For the convenience of kernel hackers like @comex and @i0n1c, we have a new redsn0w 0.9.8b3 that supports a TETHERED jailbreak for iOS 4.3.4 on all devices that have 4.3.4 except the iPad2. The vast majority of people will want to stay back at 4.3.3 because that’s where the untethered jailbreak is! There are no new features in 4.3.4 – only fixes for jailbreak exploits.
Also, this is a good time to remind everyone (since we’re still seeing confusion about this): iPad2 owners with a baseband (3G or CDMA) cannot currently use saved blobs to go back to 4.3.3 once the signing window is closed. This is unlike every other device, so don’t be confused! iPad2 owners with basebands should stay away from all updates to maintain your jailbreak!
This jailbreak works with iPhone 3GS, iPhone 4, iPad 1, iPod Touch 3G and iPod Touch 4G. It does not work with iPad 2.
