    Is it factory unlock ? You can downgrade to 3.1.3, do the shifit + restore to 3.1.3 and use tiny umbrella to kick it out of recovery when error 1015 pops up.
    Once you are at 3.1.3, jailbreak with Redsn0w 0.9.4 and point to 3.1.2 ipsw which you have to download.
    Once jailbroken, you can use snowbreeze 2.0 to create 4.1 and then do the shift + restore to snowbreeze_4.1. ipsw.

    Requirements:
    1) 3.1.2 stock ipsw
    2) Redsn0w 0.9.3
    3) Recboot

    Steps:
    1) open iTunes
    2) set phone in DFU mode (hold power and home button when phone is OFF, until the apple logo shows, release power button and hold home button until iTunes detects phone in DFU mode. You'll get a pop up from iTunes).
    3) hold shift and click restore
    4) select the 3.1.2 ipsw
    5) let iTunes restore phone
    6) upon receiving error 1015 (or any variation of), open Recboot to kick phone out of recovery mode
    7) phone should reboot to emergency call screen
    8) open Redsn0w 0.9.3
    9) select the same 3.1.2 ipsw
    10) select "Cydia"
    11) continue and follow the on-screen prompts
    12) you should then be jailbroken on 3.1.2

    If you want to get back to 4.1, download Sn0wbreeze 2.1. Create a custom fw with a stock 4.1 ipsw. Go to iTunes and set phone into DFU again and do the shift+restore to the CUSTOM 4.1 ipsw you just created. Let it restore and you should be done and JB.

    Some 3G users have experienced problems using Sn0wbreeze. If you can't use Sn0wbreeze, your only option is to stay on 3.1.2 (or 3.1.3 but they are basically the same thing).

    Edit: darn it Yeow, you're always beating me to it.

    You'll want to set up your phone as new so you'll lose some things. Back up your photos to your computer, back up your contacts in either Microsoft Outlook, Google contacts, or something of your choice to which you can sync back to your phone. Messages I don't know how to save as they're part of the back up saving from iTunes. Apps and music you can always sync back since they're stored in iTunes.

    It's not where you download from, it's what you download with. Use Mozilla Firefox or Google Chrome to download. Internet Explorer will mess it up.

    Are you restoring to 3.1.2? If you don't have your SHSHs, that's the error it gives (but for 4.0 and up).

    You sure it's an iPhone 3G?

  13. #12

    If it's a 3GS you'll need SHSHs to downgrade.

    If you didn't get your 4.0.1 SHSHs before 08/19 then you can't get them anymore. I doubt you have them if you don't know what they are.

    Check with TinyUmbrella to see anyway. It wouldn't hurt to try.

    Go Google TinyUmbrella, install it, click advanced options, select "iPhone 3GS 4.0.1" and click Save SHSH and see if it succeeds. If it doesn't succeed and tells you it's too late, you don't have SHSHs to downgrade.
