Download 4.1 IPSW for your device from here http://www.hackint0sh.org/f127/22056.htm

Open iTunes and shift-click (alt-click on mac) on restore button, browse to the IPSW you downloaded and restore that.

Any errors: run TinyUmbrella and try the "kick out of recovery mode" option. The Firmware Umbrella - TinyUmbrella

This will wipe any data since the last successful sync that you had on the device but will get it working for you. You should be able to restore from iTunes backup to get the majority of your files back.
