    hey guys, this is my first post so hopefully somebody can help me.
    i'm on windows, and i have a 16gb iPhone 3G with firmware 2.2.1 installed. i wanted to re-jailbreak my iPhone after the upgrade, so i downloaded the quickpwn update from http://www.installerapps.com/2009/01/27/jailbreak-221/ and ran it using quickpwn. quickpwn runs fine, but when i try to jailbreak using the 2.2.1 firmware, i get an error saying "Firmware error string."

    does anyone have an idea why this is happening? i know it's a legit .ipsw file (i've used it to restore my iphone with itunes before) so i'm not sure why this is happening.

    Can't tell you why but I can tell you how to fix it.

    Start over. Restore your iPhone. Delete and re-download quickpwn. Jailbreak. ;)

    i've already restored and tried it again, but to no avail.
    i'll redownload quickpwn and the update, crossing my fingers the whole time.

    edit: thanks lp. i downloaded the new quickpwn (rather than just a patch) and it works! iphone 2.2.1 is succesfully jailbroken :D
