I updated to 3.0, and, yes, I know, but I would like to go back to 2.2. Does anyone know how to do that? I have download 2.2 .ispw software, but everytime I attempt to install it I get an error message (20). HELP!
Is your phone hanging in DFU mode when you try to downgrade? If so, download QuickPWN for the firmware you are wanting and run it. It will kick it out of DFU mode and you should be set. It works with 2.2.1, so I would *guess* it will for 2.2.
