    Hey, I'm planning on updating to 4.0B1 on my 16GB iPhone 3G! How hard is it to downgrade to 3.1.3? I'm gonna use VMWARE to install with OSX... So before I waste all this time I wanna be sure I can downgrade!

    Super simple. DFU mode and Shift-Restore to 3.1.3.

    Thanks, I just wanted to double check. I had a failed install of 4.0 and had to down-grade...

    Anyway, can I downgrade on Windows? I don't plan on keeping VMWARE on.

    I did it on a Mac, and it was simple. Not too sure about the process for PC, but it should near the simplicity since most of what i had to do was terminal commands and iTunes restoring.
