    a couple of my friends said they had done it and it worked. but i'm still not 100% sure and thought i'd post it on here to see your thoughts and to see if it actually worked.
    i have over 400 apps, 6000 songs, and around 100 videos including movies, tv shows, podcasts, and music videos. so i'm interested in this because i might be able to find a way to upgrade without restoring. i also have shsh blobs for 4.0, so that's not a problem. i just want to know if there's a way to do it.

    Nah, restoring is the only way to upgrade.

    For 4.0 you need to restore to upgrade.

    i have a similar question too
    I have ipod touch 8gb mc model jailbroken with blackrain on 3.1.2
    i want to try the jailbreak for 4.0

    i've downloaded a shsh blob from a website that is 4.0
    so do i need to upgrade with itunes first to 4.0.2 then downgrade back to 4.0? or can I just upgrade directly to 4.0 using the blob?

    also, i've recently installed itunes 10, i hope that's ok

    you downloaded a shsh blob from some website. How??
    shsh's are ecid device specific. unless the ecid on the shsh is the same as yours it won't work.
    4.0.2 can't be jailbroken unless you have a pwn4life device. (which you don't)
    so you will either have to wait for a 4.0.2 jb or 4.1 jb.

    Apple doesn't sign for 4.0
    So it will restore you to the newest firmware.
    Need to have those SHSH blobs!

    sorry, i'm totally lost on the idea of shsh

    let me start over
    I have a 8gb mc model ipod touch on 3.1.2
    I want to upgrade to 4.0 or 4.0.1 cause I read that jailbreak doesn't support 4.0.2 yet
    Is there any way to do this?
    All the articles and topics i've read talked about downgrading and saving shsh on the current firmware so i can restore back to this firmware (i.e. 3.1.2 as im using it now)
    but I actually want to upgrade to 4.0.1 or 4.0 and i haven't had the version before
    what can i do?

    change your hosts file and shift+restore to 4.0 IPSW. sorry cannot tell u were to get IPSW
    ------------------double post merged------------------
    oops. only if you have SHSH saved for 4.0. otherwise you might as well save your 3.1.2 blobs and restore back to 3.1.2 and spirit.
