    Default Re-Jailbreak

    I need to re-jailbreak but can only upgrade to 4.2.1 on my new bootrom 3GS (which is currently 4.0 (8A293), bb 05.13.04). I lost MMS functionality after userland jb (jailbreakme) and tried everything restoring it. I noticed the minimal bundle on dev-team's site, but it only mentions 3GS old bootrom. Is there a custom firmware I can use that will preserve the baseband and take me to 4.2.1 for new bootrom 3GS so I can unlock with Ultrasnow without updating to iPad's bb?

    thanks

    I just bought a iPhone 3GS jb and unlocked on V3..3 baseband 05.12.01
    I would like to run V4.? on it, but I am not sure if it is a untethered JB or if it will mess up my baseband? I don't know how to tell what bootrom it is. The phone is already activated on Bell in Canada.

    I run a Mac and can use redsn0w. My shsh blobs for V3.1.3 are saved via Cydia. I am not sure how to save them to my computer using TinuUmbrella.

    Any help would be greatly appreciated.

    Just press save SHSH in tiny umbrella with your device connected to save them to your computer.

    Check what bootrom you have with idetector

    Thanksx98car, I'll have to try tiny umbrella again, any idea how large a file it would create? I assume it would be in a hidden folder or? PS: I run Macs, do not sure if there is a program like iDetector for Mac.
    I'll try and borrow a Win machine.

    So it all depends on what bootrom I have as to the iOS I can safely JB and run?

    i.Annie, I don't know how I can check if any saved SHSH blobs for V4.1
    I don't think this phone has ever been upgraded past V3.1.3. I am going to make sure I have saved V3.1.3 again

    How large should file be?

    Follow what x98car said before. Use TinyUmbrella to check for SHSHs.

    SHSHs are saved on Cydia's server if you have any. You don't have to have upgraded to have SHSHs for iOS 4. if you ever saved them, the new firmware SHSHs will automatically be saved thereafter.

    On cydia's main page, at top it says SHSH for V4.2.1+ saved or something like that

    With new bootrom can I upgrade to an untethered JB in V4.XX or do I need to wait for it to be released, a new JB I mean

    You would need to wait for a untethered jailbreak to be released.

    But if I use iOS 4.1.2 I can JB untethered using RedSn0w on a Mac? Or no

    There's no such thing as 4.1.2, so what do you mean?

    Hello All,

    Just a quick question, In the past I have used Blackrain to jailbreak and most recently may 2010 used Spirit. So right now I have a 3GS with version 3.1.3(7E18) and modem firmware 05.12.01. So what above jailbreak should I use to upgrade. And any further suggestions are welcome Thanks...

    Do you need to unlock and do you have any SHSHs saved

    Perfect. Just download tinyumbrella from thetinyumbrella.blogspot.com and click save SHSH to make sure you have 4.1 saved.

    Since you don't need to unlock, simply run TinyUmbrella's TSS Server then open iTunes and shift+restore to a stock 4.1 ipsw. Then proceed to jb with Redsn0w 0.9.6b6.
