    I've got a iphone4 4.1 firmware and 2.10 baseband.
    It's jailbroken with limera1n.
    DONT HAVE ANY SHSH FILES SAID IT WAS TO LATE...

    I would like to know if this is possible.
    Im' trying to upgrade to 4.2.1 firmware.

    my thinking is that ill use sn0wbreeze 2.2 and create
    custom firmware use i tunes to restore with custom firmware.
    and be jailbroken with the 4.2.1 firmware.

    it says you can use ultrasnow and preserve your baseband.
    I'm not worried about that just want the firmware update.
    I can always rejailbreak with greanpois0n..?

    Also if this does work or doesnt work can i get my old firmware
    back through device restore from factory settings or from a backup ive created?

    here is were i got my idea
