    I wanna try out iOS4 on my iPod Touch (3g, 32gb), but I'm jailbroken. I don't want to risk losing my jailbreak. So can I still downgrade if I decide I don't like iOS4 after all?

    If you have backed up your SHSH blobs then yes, you will be able to.

    Open up Cydia once and if it says the device has SHSHs on file for iPhone OS 3.1.3, then you're good to go.

    Where do you check to see if you have these blobs, exactly? Because I don't see it.

    I never backed up a blob in my life personally and I went from 3.1.3 Spirit to 4.0 GM and restored back to 3.1.3 though iTunes, and I don't remember backing up blobs.

    Is this iPhone users only?
