    I am currently on 4.2.1 I would like to maintain an unteathred jailbreak.

    I was just curious if anyone could give me details on moving to 4.3.3. I have never done an upgrade with to an 'older' version of IOS so i'm not sure of the steps and where to get the files I need.

    Thanks in advance.

    Do you have Tiny Umbrella? If you don't you will need to download the latest version of TU here.

    Once you've got TU up and running, click on the advanced tab and make sure the set hosts to Cydia tab is selected. Run the TSS Server and shift restore to iOS 4.3.3 through iTunes. Anticipate an iTunes error, use the exit recovery feature of TU to boot your phone :)

    Easy peasy lemon squeezy :)

    Thanks for the info. Didn't know it was that straight forward.

    Will the method above erase any application settings? I'm assuming i will want to backup before hand, and then I can restore afterwards?

    You could shift-update and re-jailbreak but I don't recommend doing that. If you're updating to a newer firmware and jailbreaking, I personally think it's better to do it with a clean fresh install of OS.

    Where can I get the IPSW for 4.3.3? Does Apple host these somewhere?

    I am trying the same thing, but I don't have the devices SHSH files. TiniUmbrella tellsme that It is too late to fetch them because Apple is not signing them anymore.
    Does This means that I am stuck with 4.2.1 Jailbreak forever?

    What Options do I have? I would like to have a newer version with Jailbreak.
    Thankyou.
