    I have decided to downgrade due to various issues with OS 4 but I want to try downgrading to 3.1.3 if possible because it may contain a bug fix that is useful to me (apps crashing).

    I never saved sa blob because I didn't think my device needed it but I get the 3194 error from itunes and most searches either say go to 3.1.2 or refer to MC devices.

    Is there a way to downgrade to 3.1.3 or am I just stuck at 3.1.2?

    thank you.

    If you only have 3.1.2 SHSH blobs backed up on Cydia then yes, you can only go back to 3.1.2(but 3.1.3 has no new features or anything that you would need over 3.1.2). If you didn't back up your shsh blobs then you are stuck on iOS4

    I thought only MC touch 2gs needed SHSH blobs?

    I am able to downgrade on 3.1.2 though (fortunately) and a copy of itunes 9.0 in xp mode.
