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 updated RedSn0w with the ability to save iPhone unlock tickets ().
redsn0w 0.9.10b8 adds the ability to backup arbitrary directories or files from your device into a zip file on your Mac or PC. The new button is Extras->Even More->Backup and it requires your device to be jailbroken with the afc2 service enabled (most jailbreaks include that). By default it will backup your activation records from /var/root/Library/Lockdown, which is useful for everyone taking advantage of today’s SAM unlock using Loktar_Sun’s trick
iPhone Dev-Team released RedSn0w 0.9.9b9 with full iOS 5.0.1 support (no need to point to iOS 5.0 any more). New version also features support for SHSH and APTickets:
native support for 5.0.1 (no need to point redsn0w at 5.0 IPSW or use command-line args). Support automatically extends to all of redsn0w’s various functions: “Jailbreak”, “Just boot”, “Fetch blobs”, “Stitch blobs”, “Recovery Fix”
iBooks fixed in 5.0 and 5.0.1. This is a targeted fix that doesn’t remove entire sandbox mechanism. 5.x users already using redsn0w “Just Boot” can just use the new version without redoing entire jailbreak again
3GS old-bootrom owners can now create custom IPSWs without blobs
ultrasn0w compatability update (i.e. same baseband requirements) for 5.0.1 will be available on Cydia Monday
support for newer 8GB (which until now had problems with “Fetch blobs”). Thanks to @JKjeepnJeff for loaning us one of these newer i4 units for testing!
allows Windows users (not just OS X users) to use the “Custom” button to create IPSWs without baseband updates. (Update: please wait for 0.9.9b9b for this!)
accommodates APTickets in 5.x (until next Apple countermove). APTickets are crypto-verified before submitting to Cydia, just like the main blobs. Cydia server support for sending back the APTickets is upcoming. For now, use stitched IPSWs for 5.x. Due to APTickets, stitched 5.x IPSWs now require user to start in “Pwned DFU” mode
Support added for stitching 4.x blobs to iPad2-GSM IPSWs. Similar to @notcom’s TinyCFW but doesn’t require lots of RAM or a TSS-assisted restore. Won’t work for iPad2 5.x blobs (or iPhone4S at all) until a bootrom-level exploit is out
top line now shows whether (and where) a redsn0w update is available, or if the version being run is the latest. Uses DNS TXT record to alleviate any concerns about snooping
no 5.1 beta support at this time (major apps like Cydia are not yet compatible)
@pod2g has been doing a great job porting his 5.x untether…check for updates!
Owners of newer 3GS iPhones must not flash the iPad baseband. The iPad baseband will not work on 3GS iPhones built later than 2011 week 35. You have a week 35 or later device if your serial # starts with xx135.
Update #17b: Version 0.9.9b9b enables the “Custom” button for Windows users, and make the 3GS week 35 warning a more explicit part of the process.
RedSn0w 0.9.9b8 recognizes 5.0.1 beta and you don’t have to “point at 5.0 IPSW” any more. Since the IPSW isn’t public, you’ll still need to provide it once to redsn0w (Extra -> Select IPSW).
MuscleNerd has announced via Twitter that jailbreak utility RedSn0w 0.9.9b1 is released with major update and numerous new features:
Major improvements and features added to redsn0w 0.9.9b1! See update #9 at http://is.gd/6eek4Y Feedback: @redsn0w_testers
Indeed the list of new features is quite high. There are two main ones:
There is no need to download firmware any more. There is no need to push Browse IPWS button any more (but you still can).
Developers added lots of functionality to work with SHSH keys (extract, submit, download, verify, stitch etc)
However this new version does not bring features like untethered jailbreak for iOS 4.3.5 or iOS 5.
Due to some possible bugs we still recommend to use the old RedSn0w 0.9.8b7b, but the new 0.9.9b1 is worth seeing and playing with.
Here are links to our RedSn0w 0.9.8b7b iOS 4.3.5 jailbreak tutorials:

Here is the full list of features from DevTeam:
Update #9: A bunch of new features!
uses DFU mode to try to automatically determine which device and FW you have
fetches pieces of public IPSWs from Apple (once). Non-public IPSWs must be provided manually (once). It then caches those pieces for future use.
“Just boot” is a tethered boot. Uses whatever “Preferences” you’ve set for boot logo and kernel boot-args
“Pwned DFU” puts your device in a pwned DFU state for some of the iTunes stuff detailed below
“Recovery fix” gets past 1015 types of errors (when baseband portion of restore fails). Should work on iOS5 beta too
“Select IPSW” is for picking non-public IPSWs, or overriding auto-detection
“SHSH blobs” has a bunch of options…
“Fetch” – fetch current PARTIAL blobs on device. Should complete in under 10 or 15 seconds. Puts the set of PARTIAL of blobs on your computer as a plist. Checks if Cydia already has a full set for this device and build. If not, it submits this PARTIAL set and returns Cydia’s acknowledgement or rejection
“Verify” – cryptographically verifies existing blob files from either redsn0w, TinyUmbrella, or Cydia server. You can select a whole bunch of blobs to verify at once if you want (like the TinyUmbrella directory)
“Submit” – both verifies and submits one or more blob files to Cydia. This lets you copy your entire TinyUmbrella cache of blobs up to the Cydia server
“Query” - queries the Cydia server for all available FULL or PARTIAL blobs for a given set of ECIDs
“Stitch” – stitches either FULL or PARTIAL blobs to a STOCK or CUSTOM IPSW
Stitching is NOT yet supported on iPhones! Need to work out the baseband part of the restore process.
FULL blobs stitched to a STOCK IPSW gives you a completely self-contained signed IPSW that iTunes will accept without any tricks (no need to go into pwned DFU mode, no need to start TinyUmbrella TSS server, no need to redirect to Cydia server for blobs)
PARTIAL blobs stitched to any IPSW requires you to go into pwned DFU mode before running iTunes. No need to start TU or use Cydia though.
Stitching either FULL or PARTIAL blobs to a CUSTOM IPSW also requires a pwned DFU start before iTunes restores. No need to start TU or use Cydia though./li>
Will eventually support fetching the blobs directly from Cydia instead of a file on your computer
