    Default 3g - 4.0 rollback help
    Hey, I've got an iphone 3g that's currently running iOS 4.0. I'm trying to roll back to 3.1.3 so I can get back to using all of my old jailbroken apps. I have 3.1.3 ipsw and itunes When I shift+restore I get the "Iphone could not be restored, firmware is not compatible" message. Please help!

    yeah, my phone is currently JB but so many apps aren't compatible yet that I'd like to go back. Also, my phone ran much faster on 3.1.3

    Download the 3.1.3 firmware from the downloads section. Then hold "shift" if you're on a PC and click restore to chose the 3.1.3 firmware you just downloaded. If you're on a mac hold "option" and click restore.
    Have they released the jailbreak in the app store yet?
