    Help! I foolishly updated to OS 4 and do not like it at all. How do I get my old 3.1.3 back? I've searched the forum but must have missed the answer. Use short words and speak slowly...I am a noob. Thanks.....

    I did the same thing. I looked on YouTube and did a search on how to downgrade it. All the thing they suggested didn't work. I found out that currently it isn't possible. iOS 3.1.3 required iPhone to 'call home' and Apple will not approve a downgrade of the iOS. Does that make sense? I think if you wait a while, someone will figure out a work around.

    Its not possible to downgrade any 3GS model to previous firmware unless you have SHSH's saved for previous firmware builts.
    If you dont know what those are then you probably dont have them :D
