    about a week or so ago, I decided I was going to give jailbreaking a try. My friend has always done my iphone and ipod touch. Ipod touch 2g hadn't been updated in, well since I first bought it so it was running 3.1 I believe. Of course, I just jumped right in without doing my homework and began the process. I was following a tutorial and using redsn0w and restored using the firware I wanted to end up at (I just picked the last one available for itouch 2g which seemed to be 4.2.1) and restored through itunes with that ispw file saved to my pc. All went through fine and then all that was left to do was jailbreak. Then I realized the power/sleep button was broke so I was stuck with non jailbreakable ipod now since I can't enter DFU mode and jailbreak me doesn't support the firmware I restored to.

    Well, a week or so later and TONS of reading, I now know all about shsh blobs and why I need them, etc. I had never done my own jailbreaking and never knew cydia would save them automatically but checked on my iphone and sure enough it had all of mine. My friend must have set it up to save them for me knowing I'd need them.

    I googled and googled to see how to check and make sure cydia has them for my ipod touch as well but using TU it says the old "Sorry youre too late" for all the shsh it searches for.

    Sooooo, my question is, if cydia doesn't have them, and I need them to change firmware to anything besides the latest, how was I able to go from 3.1 to 4.2.1 when apple isnt signing 4.2.1 anymore? Do you only need shsh for downgrades then? I was under the impression you need them for ANY firmware apple is no longer signing. Does this mean I may have the blobs for this on cydia even though TU says I dont? Any other way to find out?

    Apple is still signing 4.2.1 for that particular iPod, but not for the older models, as their hardware can take advantage of more recent firmware.

    SHSH blobs are indeed only needed if you were to want to downgrade. Not sure how to find out about already having SHSH blobs for that firmware unless you've run Cydia on that iPod already.

    Also, Tiny Umbrella may be able to throw your iPod into DFU mode instead of having to hold down the Sleep/wake + home button. Not sure though, as I have never used the program.

    Thanks, I was getting confused as I was also dealing with my iphone 3gs at the time and knew they were no longer signing 4.2.1 for it, but just overlooked that they still were for the ipod touch 2g. As for DFU, I messed with the button enough that whatever was making it stick down, somewhat released and got it into DFU and successfully jailbroke. Now my BF's ipod touch is happy again.
