    How do I downgrade my iPhone 3G on FW 4.1 to 4.0/4.0.2? I have read that I should use Tiny Umbrella but it is only for 3GS/4. I have no idea if my SHSHs are saved or what they are. Any help?

    Jakk, downgrade to 3.1.3 and jailbreak with Pwnage tool/Sn0wbreeze. Then creƤte a custom 4.0(.1) and restore with it.

    U can only downgrade if u r having shsh
    For 4.0
    Open tiny umbrella click advance option then select ur device and fw 4.0. If it's say cydia hav ur shsh then only u cn downgrade

    I did exactly this and it said 'SHSH SUCCESSFULLY saved! Click here to open'.
    So this means I can downgrade to 4.0 by running TSS server, opening iTunes then Shift+Click restoring to the 4.0 FW?

    EDIT: Can I just Shift+Click restore to 3.1.3 as well without the SHSH? Is 3.1.3 better than 4.0?

    I'll try 4.0 before 3.1.3 because some things on Cydia are iOS 4 only.
