    Default unlocked 3GS oldbootrom 3.1.3 -> 4.1 possible?

    I have searched many times in different forums, but I couldn't find any case that is similar. Please point a noob to right direction.

    OK. Recently I was able to score a used 3GS at a great deal.
    The previous owner didn't know much about phones so it was never updated.

    It is on.
    Baseband: 05.12.01
    Bootloader: 6.4
    Model: MB716

    So what I did was.
    1. I went to JailbreakMe to jailbreak the phone (although it was on 3.1.3, I gave it a try and it worked)
    2. I unlocked it using ultrasn0w 1.1-1

    So far everything is working well. But, I want to install 4.x software on it. So, I found sn0wbreeze was the way to go, so I created custom rom.

    BUT HERE'S THE PROBLEM
    Sn0wbreeze says that I need to prepare it with either
    a. Spirit2Pwn if you are running 3.1.3
    b JBme2Pwn if you are running 4.0 / 4.0.1


    I am on 3.1.3 but I jailbreaked with Jailbreakme.com. And to make this worse, the repository is down.

    How do I prepare my iphone for custom rom? Does anyone have similar experience?

    Please help.

    You will not find support for sn0wbreeze or any of the ih8snow applications on this forum -- we've detailed why in hundreds of posts throughout the forum.

    It is highly recommended that if you are doing this on a PC, you use redsn0w or greenp0ison to jailbreak 4.1. In a pinch if neither of those work, you can use limera1n. This will allow you to jailbreak with one of the supported tools.

    If you're on 3.1.3 and you want to go to 4.1, and you DO NOT rely on an unlock for your phone service and you DO NOT care if your phone is or is not unlocked, you can restore to 4.1 as normal, upgrading your baseband (relocking it if it's unlocked), and use redsn0w/greenp0ison/limera1n to jailbreak. Note that the baseband in 4.1 CAN NOT be unlocked right now, so this is not a valid method if you rely on an unlock.

    If you rely on an unlock, the legitimate way is to spend the $129 and get a copy of Mac OS X, download Virtualbox and install it, and use that as a 'hackintosh' of sorts to create the custom firmware file with PwnageTool. Alternately, if you know someone with a mac, you can do this on their Mac. It is NOT recommended that you download a 'pre-pwned' .ipsw -- you do not know what utility they used to make that .ipsw, and there have been many cases where people put fake custom firmwares to entice people into upgrading, only to find out that they have upgraded to a stock firmware and their phone is locked. Don't take the chance!

    The biggest concern you'll face is that if you do not have SHSHs on file and anything horrible happens, you're going to be stuck with the only option being to upgrade to a factory 4.1 -- which will lock the phone.

    In any case, you can definitely jailbreak, and we all recommend you do so without using the ih8snow tools -- if you're curious why, just do a search for ih8snow, you will be unable to find a thread where the mods don't step in and explain why we do not support those tools.
    The preceding forum post has been brought to you by the letter "N" and the number 42.
