    I have searched and just want to confirm:

    I am pretty sure I have my SHSH backed up to Cydia, but going to check tonight. I also am going to try to locate the Umbrella program and download my SHSH for posterity.

    Then, I should be able to upgrade to 4.2.1 and JB with redsn0w, but if I don't like it, I can download a copy of the 3.2 firmware and with my SHSH blobs saved, I should be good to go?

    Am I missing anything?

    If you have your SHSHs for 3.2.2 or 3.2.1 you can downgrade to those firmware not problem all you need is TU and the firmware. If you have an iPad 3G your BB will be upgrade and that one is not downgradable just as side note.
