    hi, ive got an unlocked iphone 3gs JB with redsn0w running ipad baseband. i replaced my hard drive on my macbook, and have not had to reboot my iphone since. it died last night, and now i need to reboot with redsn0w, but itunes doesnt have an ipsw file saved anywhere for this iphone. I thought that once i registered my iphone with itunes, an ipsw file was created?
    i tried using a restore ipsw downloaded from the internet, but had no luck in redsn0w.

    will i have to restore? i dont want to, because itunes will make me upgrade the phone.

    Wow, you're way off on alot of things you posted.
    Slow down and research a few things.
    Then go here and download GP to JB untethered your device.

    Assuming you're on 4.2.1 firmware right.
