    Default Jailbreak/unlock 3GS old boot rom, from 3.1.2

    OK, so my wife's phone has never been jailbroken and I wanted to update her to 4.0 and jailbreak and unlock in the process. (She's going to Europe in September and wants to use my prepaid SIM) Her phone is the old boot rom and I have the SHSH blobs for her phone for 3.1.3 and 4.0

    My 3GS has been jailbroken since 3.1.2 and I've already updated it to 4.0 using, both using custom bundles with Pwnage.


    The way that I see it, I have two paths that I can go:

    1: use Pwnage to build a 3.1.2 firmware bundle and then use Pwnage to put the phone into a mode that will allow me to restore it. When I'm done with that, build a custom 4.0 bundle and restore it with pwnage again. (can I do this without the SHSH blobs for 3.1.2?)

    2: update to 3.1.3, use Spirit to jailbreak it and then Spirit2Pwn. Once that's done, build a custom 4.0 bundle with Pwnage and load that up with itunes.
    (I'll have to use the SHSH blobs to do this I suspect as Apple won't allow me to upgrade to 3.1.3 at this point)

    Once I'm on 4.0, I can use Ultrasn0w to unlock the phone.


    Any recommendations on which path is the best?

    Pwnage. Pwnage Pwnage Pwnage, definitely.

    Spirit is a great jailbreak and Spirit2Pwn is a great addition -- but I only recommend using it if you don't have a 3.1.2 jailbreak. PwnageTool makes a 100% stable and reliable, jailbroken .ipsw and restoring an already jailbroken firmware is definitely better than jailbreaking a running firmware.

    Ultimately, both paths will lead you to where you want to be -- on iOS 4.0 with an unlock, but PwnageTool will likely be the easiest and most reliable way to do so.

    You're correct, Apple is only signing 4.0.1 for the 3GS right now -- you'll need SHSH to restore to anything earlier.

    Good luck!

    Thanks

    One last question. I don't have the SHSH blobs for her phone for 3.1.2, but I do have them for 3.1.3. I assume that I'm just performing without a net so to speak but that with Pwnage I can get in and restore a 3.1.2 custom bundle?

    If not, then it looks like I'm onto the 3.1.3 spirit and then spirit2pwn path?

    correct?

    What OS is her phone running right now? If she is running 3.1.2, then you can still use pwnagetool even though you don't have SHSH blobs for 3.1.2

    Otherwise yes, Spirit and spirit2pwn.

    Still at 3.1.2, never upgraded it since we got it last year.


    Thanks, so it looks like Pwnage is the best route. use Pwnage to put it into firmware upgrade mode and get me in, then restore custom FW bundle (that I already built for my 3GS)

    A final question, i promise:

    Once I get Pwnage to get me in, do I have to restore my custom FW bundle from 3.1.2 to the phone and then go to the custom 4.0 bundle or can I go straight to 4.0?


    thanks again!

    You should be able to go straight to custom 4.0 ipsw - once you have jailbroken 3.1.2.

    thanks again!
    As mentioned pwnagetool can jailbreak an old bootrom 3GS running 3.1.2, however redsn0w and blackra1n can also jailbreak this OS and may be faster, less hassle. You just need to get the iPhone jailbroken at 3.1.2 so it will accept custom IPSW - it does not matter which tool you use to do that.

    This will not work for a new bootrom 3GS. The new bootrom 3GS cannot accept custom IPSW built with the 24kpwn exploit.
