    True that!

    Especially true for Spirit JB, because if you have pwned the NOR you can still restore to custom after you get stuck at boot logo; with Spirit you are essentially screwed the moment something goes wrong and have to restore to official 4.0 and wait.

    Mostly iPhone hacking: OLD BOOTROM + Spirit => 4.0 JB

    Couldit apply to my current situation? I don't have any BLOBS though.

    Thanks again!
    Most likely not. As Olethros says, unless your friend was sitting on this unopened 3GS since prior to September of 09, the odds are you've got the new iBoot (359.3.2), which cannot be pwned nor jailbroken on iOS 4.0 right now, and trying the steps in the article you linked to will most likely result in your phone turning into an expensive brick until you restore factory iOS 4.0 to it...

    I know it's been said before in this forum, but we really can't stress enough how important it is to know your bootrom version when you start playing with the new jailbreak utilities. Perhaps the new version of tools will find a way to detect this and let you know without being in DFU mode, but ultimately, it's worth the time it will take for you to get it and find out. If the options are to spend a little bit of time, get the real answer, then have a jailbroken phone vs. guess and get it wrong, and end up with a locked phone you can't return -- I know which of the two I'd prefer.

    Good luck!

If the serial is lower than xx940 you can be pretty certian. Anywhere between xx940 and xx945 is a maybe and anything above that - including for example XX010 is 99% chance new bootrom. The problem with this approach is that most people don't get that the 3rd digit is the year number and that 0 = 2010 whilst 9 = 2009. So it can be deceptive to the uninitiated.

    If you have been sitting on the device (unopened) since last September, then you are probably okay.
    Thanks for all your replies.

    3rd, 4th and 5th digits==932, so I guess I got the old bootrom.

    So if the fw ver==3.1.2, then I should go the ultrasnow + pwnage 4.0.1 route, and if Fw ver==3.1.3, then I should go the Spirit + spirit2pwn route?

    In any case, the issue is probably moot in my case, since I'm on the road again and my still unopened BNIB 3gs is back at home probably by the time I get back, there will be an updated Spirit jailbreak version.

    All your comments are welcome. Thanks again!

    If it's that old, it is going to be running iOS 3.0.1 (or less likely 3.0)

    Redsn0w to jailbreak - then reload with Pwnagetool custom IPSW.
    Ultrasn0w for unlock. It is safe to let pwnagetool upgrade the baseband to the 4.0 baseband - ultrasn0w can still unlock that.

    Thanks Olethros for taking the time to reply.

    I don't need unlocking. Given this fact, which steps you suggest I take? My final objective is to eventually get to 4.0 jailbroken.

    Thanks!

    Still recommend redsn0w to initially jailbreak and then pwnagetool 4.0.1 (use advanced mode and turn off activation, turn on baseband upgrade) to go straight to 4.0 jailbroken from 3.0.1 jailbroken with redsn0w

    So that means that if I have 3.0.1, I don't need the blobs to follow your recommended process? That would be outstanding news for a noob like me!

    Thanks *A LOT*

    You don't need blobs - but you need to be more careful without blobs. If you install something that causes your jailbroken iOS 4 phone to crash and require a restore, you need to always use custom IPSW. You have no option to restore any original apple IPSW that can be jailbroken.

    Thanks for your help.

    3 dumb questions if you don't mind:
    • Why do I need to jailbreak to 3.01 and not go directly to 4.0?
    • Do all the applications / data get wiped out in between jailbreaks? Or we're affecting different "partitions" or memory areas when we perform the upgrade from 3.x.y to 4?
    • I guess I should not install cydia the first time (RedSn0w) since it will be reinstalled the second time around?


    Thanks again!

    Right now there is no way to directly jailbreak (or pwn) 4.0 on a 3GS - that is why you need to jailbreak at a 3.1.2 or earlier and then use only pwnagetool ipsw - if you restore or upgrade to an unmodified apple ipsw this takes you off the pwnagetool train and you need to use cached SHSH to go back to 3.1.2 or earlier and start the jailbreak again.

    Redsn0w does not wipe a thing. Pwnagetool deliberately doesn't support making a custom ipsw that "upgrades" it only makes one capable of a "wipe and restore". The justification for this is that Cydia can't handle keeping track of what it installed across an upgrade. This is also a bit strategic as it is not always clear what Cydia packages will work without modification on a newer iOS version. So this minimises chances of failed upgrades.

    You can 'restore from iTunes backup' after you load the custom 4.0 ipsw. I generally don't recommend this - especially when jumping to iOS 4.0. Some people have experienced poor battery life and instability that is resolved by not restoring from iTunes backup. In your case as you are not planning to install any jailbroken sw at 3.x I would recommend you use the 'restore from iTunes backup' option and just keep an eye out to see if you notice any dramatic battery life problems.

    Yes that is correct.
