    3gs 4.0.2(8A400) bb 5.13.04
    New phone from store, never jailbroke, no SHSH's, have wifi working.
    I want to Jailbreak and unlock. From what I read it seems that this can't be done with Snowbreeze. The phone doesn't meet the prerequisites listed. Please tell me that I wrong and can jailbreak & unlock my phone.

    **iPhone 3GS (old boot)/upgrading to 4.1**
    Preserve baseband/Sn0wbreeze Method (Windows only):
    Prerquisites:
    1) must be already jailbroken by non-userland jb on current fw
    2) this excludes spirit and jailbreakme
    3) if device is jb with spirit or jailbreakme, this process cannot be done
    4) if SHSHs are saved for 3.1.2 and you're currently jb with spirit or jailbreakme, this can be done
    5) follow the above instructions for downgrading the 3GS to use the SHSHs to get to 3.1.2, then jailbreak with Blackra1n before following the below steps

    Default Are my ducks in a row?
    I read this whole thread, and I am ready to take the plunge. First, I want to outline what I think I have to do, and hopefully one of you fine gurus can either confirm that i am pointed in the right direction, or repoint me in the direction I need to go.

    I have a 3GS, 32 with the following:

    Version 4.0 (8A293)
    AT&T 7.0
    Modem Firmware: 05.13.04

    I have SHSHs on my computer with TinyUmbrella, 3.1.0 all the way to 4.1

    From what I can glean from the HowTo, I am both jailbreakable, and if I maintain the baseband, I can unlock.

    Do I need to unlock? Not really. But not sure how long I will keep the phone, and I can sell for more unlocked, I think.

    So, it looks like I need to do the following, correct me if I am wrong:

    Step 1 (From the first HowTo post)
    **iPhone 3GS (both old and new boot)/downgrade from 4.x to 3.1.x** ( I have the SHSHs)
    I should restore to 3.1.2 and then use BlackRain to jailbreak.

    Step 2
    **iPhone 3GS (old boot)/upgrading to 4.1**

    Preserve baseband/Sn0wbreeze Method (Windows only):

    Then I can run ultrasnow and unlock again.

    Does look right for my system version/baseband?

    Thanks a lot, I can't wait to get started.

    Michael

    Michael,

    If I were you I would get redsnow and use it to put your phone into pwnd dfu mode only. From there, install a downloaded custom firmware from the internet created with Pwnagetool without hacktivation.

    There is a guide on iclarified for this.

    I'm sorry Michael, I haven't had time to update the guide. Since you don't need to unlock, it's very simple. You can simply update straight to 4.2.1 and jailbreak with Redsn0w. If you have the old boot, that's good since it won't be tethered. If you have new boot, you can shift+restore to 4.1 with TinyUmbrella's TSS Server running (to bypass error 3194) and jb with either Limera1n or Greenpois0n.

    Edit: new boot to 4.2.1 is fine too, but if you don't want to deal with a tethered jb, I'd suggest 4.1.

    Thanks to eyerobot and I.annie. I went ahead and did as I outlined above. It went fairly smoothly and I am now at 4.1 and jailbroken and unlocked!

    I was wondering why 4.2 wasn't in the tutorials at the beginning, but since you mentioned, can I go from 4.1 to 4.2 and have not only JB but keep my unlock as well?

    I doubt it would be as intricate as what got me to where I am now.

    Thanks again for all the great info!

    Michael

    4.2.1 can be jailbroken but only tethered with redsnow. This will also update your baseband so.

    just a quick question
    I don't plan on unlocking, but does having different basebands do anything other than decide if you can/cannot unlock?
    I'm on iPhone 4, 4.1, 02.10.04
    Is that good? and if it is, how can i preserve it in future updates
    thanks in advance

    They sometimes have bug fixes, battery/signal improvements in the baseband updates. Nothing too major though I dont think. You can always preserve an i4 baseband with tiny umbrella or pwange tool once new versions of those tools come out supporting 4.2.1 for i4.

    Use custom firmware bundles to retain unlock capabilities. A CF completely removes the BB update from the ipsw.

    There are few technical reasons to update the BB, it's more of a Apple twarting unaithorized unlocking.

    2.10.04 baseband is not unlockable at the moment, but an unlock will definately come long-before the newer BB version found in 4.2.1.

    FYI: My 3GS baseband (4,26,x) is 5 or 6 versions out of date and still going strong

    I though you could only use CFs with pwnagetool, which is only for mac

    If you can get hold of a custom firmware made with pwnage tool, you can just as easily restore to that on a PC, just need to use redsnow to enter pwned dfu first

    Custom firmware can be used on any phone. This is the preferred choice for people wanting to preserve an older BB. When TU came along, it provided a second (and faster) option for ip4. But TU had some issues with the latest iOS ... so the fallback method is PT.

    Yup, agree with Mes there. Much less margin for error with pwnage tool.

    Also, snowbrerze (not always current) is the PC version for buildind custom firmware. Many like to build it w/PT, SB.... but load it using Redsnow/iTunes to get around the Mac/PC issue.

    That sound good, I'll probably stay on my current fw until a untethered jb comes out for 4.2.1, then I might look more into snowbreeze
