    Figured that would be the issue for some. For me, I was eligible to back to 3.1.2 & I think we have to use PwnageTool 4.01 to jailbreal.

    Don't really know but I'm gonna take the plunge & test it out right now see where it gets me.

    I got one question for you tough. Since you were able to downgrade, is everything functional as a normal phone (AT&T wise) and does Cydia load or does yours crash on opening?

    Hi guys,

    I have an iPhone 3GS updated to ios4 via itunes, which i'm trying to downgrade to 3.1.2.
    i tried to do this on both windows and mac and couldnt get it to work.
    instead of getting error numbers (1015, etc), i have a message that simply says "The iPhone could not be restored, this device is not eligible for the requested build".

    I correctly edited the "hosts" file as instructed, and i am using an official 3.1.2 ipsw file.
    Any suggestions?
