    Lightbulb Jailbreaking 3GS firmware 4.2.1

    Hi I have a iphone 3gs 16gig currently running 4.0.1 jailbroken using jailbreak me, now I am willing to update it to 4.2.1 and still keeping my jailbreaking capability and I am not sure how to go about doing that. Please help.

    You've left out two vital pieces of information. Without these I can't give you a very accurate answer.

    1. Old or new bootrom? Bootrom - The iPhone Wiki
    2. What SHSH do you have saved? Use TinyUmbrella - The Firmware Umbrella - TinyUmbrella to find this out.


    Plus, you haven't said whether retaining the ability to unlock via ultrasn0w is important to you or not.

    Without the bootrom/SHSH information, the only answer I can give you is that 4.2.1 is going to be a "tethered jailbreak" for you - this is not very practical.

    Provide more details or Wait for a better jailbreak.

    Hi

    Bootrom 359.3.2 which I think is new.
    Saved shshs are 4.0, 4.0.1,4.0.2 and 4.1.
    And yes it would be great if I could unlock it.

    Thanks for the prompt reply.

    Yes new bootrom. That means tethered jailbreak for 4.2.1 (which is why I strongly recommend you don't try 4.2.1)

    Use 4.1 instead via Pwnagetool iClarified - iPhone - How to Jailbreak Your iPhone 3GS Using PwnageTool (Mac) [4.1] - that will keep your ability to unlock and give you an untethered jailbreak.

    any way to do it on windows, the reason I am taking all this pain is the battery does not last very long from few days now and I am wondering its because of IOS.

    Really appreciate it.

    This question is so incredibly common - I'm sorry - the answer is no. Pwnagetool is mac only.

    Your options are: run OS X in virtualization, or find a friend with a Mac and use their computer to make the IPSW.

    Then run redsn0w 0.9.6 - beta on your windows machine. and choose the "pwned DFU mode" option. Restore the custom IPSW and you're good to go.

    Don't simply download a custom IPSW from the internet . You cannot trust that they are what they claim to be.

    Not trying to completely threadjack but I was wondering if somebody could provide me the best possible solution to get my phone to at least ios 4.1

    iPhone 3gs 32gb
    Old Bootrom
    Need Unlock
    IOS 4.0
    Modem Firmware 04.26.08 (Yes that old, been custom firmwaring all the way through)
    shsh saved through cydia from 3.1-4.1

    I would normally just find a custom firmware but a lot of unstable custom firmwares out there. Also looking to create my own custom firmware through snowbreeze but just wanted to see the best option. Untethered JB please.

    Thanks!

    Do you have a 4.1 SHSH saved?

    You can get an untethered jailbreak on 4.2.1 if you use pwnagetool 4.1.3

    The other strategies you suggested (downloading custom ipsw from untrusted source or using sn0wbreeze) are not recommended.

    Find a way to run pwnagetool yourself. A hackint0sh virtualbox install for example.

    While this probably will work, we don't recommend sn0wbreeze.
