    For you MC model IPT, you don't need to worry about the blobs.

    Yeah, iOS4 has soft SHSH blobs for the older iDevices. So you can still restore to anything below 4.0 without SHSH blobs but everything above that will need them backed up

    But I had absolutely NO problems downgrading to 3.1.2/3 from 4.0 without blobs, as well as many others.

    Hello everyone, I just have a quick question about those SHSH Blob files for the Ipod touch 3G.
    Is it possible to download them or do you have to back-up your own files?
    I accidentaly upgraded to the 4.0 firmware with my Ipod Touch 3G, from 3.1.2 JB. Now i can't downgrade to 3.1.2 because it gives me a 3194 error when controlling with apple server.
    I've read abit on forums etc, but not much help tho.
    Is it possible to downgrade IPT 3G 4.0 firmware to 3.1.2 at the moment with iRecovery thing? Please help me out ^^,

    Best Regards Anton~

    The 'soft' shsh blobs have only been included since 4.0. Check out the blog post about it here
