    I'd like to update my jailbroken iPod 3G (3.1.3) to iOS4 but I'm not one hundred percent sure of the process.

    This is what I would do:
    -Backup my iPod to iTunes
    -Download 4.0 firmware
    -Shift click restore and choose that firmware file
    *At this point should I choose to restore from backup or a clean install?*
    -Re-jailbreak once the new spirit is released

    Would this work properly and would I get a fully functioning install of iOS4? If I choose to restore from backup, could this affect performance? Would I lose all app data (saved games, high scores...) when I restore? Am I forgetting anything?

    Take out the link. It's illegal and we are not allowed to talk about it here.

    And do not restore from a backup.

    Make sure you back up your SHSH Blobs incase you want to downgrade.

    Sorry, I didn't know about the link...

    I've backed up the SHSH blobs with the "make my life easier button" in cydia. So I should make a clean install? Wouldn't I lose all my data by doing so?

    Do a backup first. It will restore all your settings and app data. But you will have to but in all your apps and music and other stuff manually.

    OK, thanks for the help. Just to make sure I've got this straight : I make a backup, then restore with 4.0 firmware and make a clean install, and when I sync the app data will be restored from the backup?

    Full instructions:

    1. Make sure your SHSH blobs are saved.
    2. Follow this guide, making sure when you sync it makes a backup.
    3. If you wish to downgrade, follow this guide.
