    You can't unless you have the SHSHs backed up in TU or Cydia. I think Cydia keeps backups of all firmware versions regardless of which ones you're on, so set your hosts files to point to surik's servers and try upgrading/restoring to 4.0.1. (http://www.theiphonewiki.com/wiki/index.php?title=Firmware is where all the firmware versions are)
