    I'm trying to use redsn0w 0.9.4, for ipt2G's. I have an MB and 3.1.3. When I select my 3.1.3 IPSW, it says "Unable to recognize specified IPSW". What is wrong?

    if you're jailbreaking 3.1.3 on MB ipt2G, you need the 3.1.2 ipsw.

    Wow, I just restored and updated to 3.1.3. So I don't have a 3.1.2 IPSW. I tried downloading one, but it didn't work. Am I screwed?

    Um...probably. Is 3.1.2 a paid firmware upgrade whoever's reading this?

    Never mind i thought i saw to use the 3.1.2 IPSW.

    If you have already jailbroken i would downgrade to 3.1.2 if you have it, it wouldn't be paid if you have 3.1.3.

    Otherwise ive seen a lot of problems on 3.1.3 jailbreaks. the IPSW files are usually located in C:\Documents and Settings\<Username>\AppData\Roaming\Apple on XP
    and C:\Users\<Username>\AppData\Roaming\Apple

    You must have show hidden files and folders and 3.1.2 should be in there if you had it before
