    i have two iphone 3gs
    first one is bought in this summer. running 4.0, i saved SHSH in cydia and i also learned how to restore the phone without getting upgrade by itune

    the second one i just bought from ebay is iphone 3gs "4.1", which is not yet jailbreakable

    Im wondering if i can use the method above(restoring the phone by using 4.0 firmware from modmyi) to downgrade my new iphone 3gs 4.1 ios.

    At the iPhone hacks section.
    Only if the new 3GS has SHSH saved on cydia in order to downgrade it.
