    Hi guys, I'm currently using an jailbroken iPhone 4 with a 4.0 firmware.

    I would like to upgrade my firmware to 4.2.1 , I have saved my shsh on 4.0 once only a long time ago.

    Now in the pic I have attached, would I able to upgrade to 4.2.1?

    If it says you have SHSH, you should be able to restore to 4.2.1.
