If you checked out our RedSn0w 0.9.9b1 video walkthrough, you saw for yourself how much of a drastic change the latest version is.
One of the most compelling features added to the new RedSn0w, is the ability to ‘stitch’ your SHSH blobs to their corresponding firmwares. This makes it so that you have a self contained means of downgrading firmware, well after it stops being signed by Apple.
Even better, is the fact that it’s completely standalone, meaning you won’t have to do any trickery in order to get iTunes to let you downgrade. By stitching an SHSH blob to a firmware file, iTunes is none the wiser.
Check out our full tutorial and video walkthrough of this incredibly handy new feature…
Note: Right off the bat, let me just say that this doesn’t work with the iPhone just yet. On their blog, the iPhone Dev Team states: “Need to work out the baseband part of the restore process…” Since iPhones use basebands, stitching isn’t compatible just yet.
The good news is, if you’re an iPod touch user, this should work fine for you; I actually created this tutorial using a 4th Generation iPod touch. Theoretically, the iPad Wi-fi should be supported as well, but I wasn’t able to get RedSn0w to recognize my SHSH blobs from my iPad 2.
Step-by-Step Tutorial
Step 1:Launch RedSn0w 0.9.9b1 and select ‘Extras’
Step 2: Select ‘SHSH blobs’
Step 3: Select ‘Stitch’
Step 4: Select ‘IPSW’ and choose your firmware.
Step 5: Select ‘Local’ and choose your SHSH blob. Note, you can use a tool like TinyUmbrella to save your SHSH blob(s) to a desktop location.
Step 6: Wait until RedSn0w finishes stitching the blobs. Upon completion, you will get a message indicating that stitching is complete.
Step 7: You should now see a newly created IPSW firmware file in the same location as the original IPSW. Save this in a safe location.
Step 8: Now that you have your Custom 'stitch' firmware with your SHSH Blob, please keep it ready for the upcoming version of Redsn0w.

Is this a one shot use of blobs or can u repeat the process with the same blobs..e.g. If I stitch a firmware can I do another with the same blobs or are they permanently attached to the firmware?

No it isn't just a one shot. You can create as many custom firmware as you like with same blob. Redsn0w just make a copy of your blob and stitch to your selected firmware.

Am i right in thinking that ifatih does this allready with the ifatih blobs you can add to a signed ipsw or is that wrong ive got 4.33 5.0 and 5.01 now which are all patched with my blobs from ifatih or is this different ?

Yes you are completely spot on except that some people saved their blob with tinyumbrella and ishshit. So this give them the option of adding it to the firmware.
Secondly not all people have PC. So this give mac users the same facility as well.

Thank you i managed to get all of them with tu and from 4.3 onwards with ifath thats good to know also that the other sw will work for mac users tbh though i havent got one so that would not have crossed my mind.
with ifaith you can only make a custom signed ipsw for ifaith shsh blobs, but redsnow will make your TU shsh blobs useful so that you can make signed ipsw with redsnow with tu shsh blobs and apticket. so u can restore to 5
click the thanks button!!!
