    my phone has stock firmware 4.3.2 on it. baseband 05.16.02 ( not jailbroke or unlocked) and i know i have to use ipad baseband 06.15 to unlock

    i wanted to upgrade the stock firmware to 4.3.3 and then use redsnow to jailbreak/unlock.

    can i just open iTunes and on the restore page, click shift then restore and pick my stock 4.3.3 firmware and it will install it? i just don't want to mess up the phone..

    thanks

    You can restore to a stock 4.3.3 if you have an SHSH for it. Download the firmware, edit your hosts file, shift+restore, kick it out of recovery mode with Fix Recovery, then jailbreak with redsn0w and unlock with ultrasn0w.

    If you don't have the SHSH, you can't restore to 4.3.3.

    thanks for your reply...sorry for the late reply....there were no SHSH to restore to 4.3.3. So the end result is i ended up downgrading to 4.1 first, then used redsn0w to jailbreak and cydia and ultarsnow to unlock....worked like a charm... Apple is still signing 4.1 and possibly 4.2.1.
