    I don't think you can downgrade if you didn't back them up.

    You can get back to 4.0 though. Plug your iPhone into your PC and turn the sound up.

    Hold home and power until you hear Windows make a noise
    Let go of power but keep holding home until Windows makes another noise
    Open iTunes, hold shift and click the restore button
    Restore to the 4.0 firmware

    Downgrade iTunes to 8.2. This one works for me

    Are you using a firmware other than 3.1.3 to downgrade?

    The firmware IS installed. But in recovery mode loop (because of the baseband). You can get it out of it! Here is a tut...

    You will need to use a program called iRecovery. If you need to find it, google is your friend.

    once downloaded, open it up in terminal or command prompt and type in the following, hitting enter after every line.

    iRecovery -s

    setenv auto-boot true

    saveenv

    reboot

    Except on mac you'd have to
    Code:
    ./iRecovery -s
    
    instead
