okay, so i installed the new 3.0 firmware, and honestly, i hate it. so, i want to go back to 2.0. i tried holding down shift in iTunes and clicking restore, then clicking my restore file (iPod1,1_2.2.1_5H11_Restore.ipsw). didn't work. i get the error "The iPod "iPod" could not be restored. An unknown error occurred (1600)". same thing happens when i hold down shift and click Check for Update. is there ANY possible way for me to revert back to 2.0? btw, i also made sure my iPod was in DFU mode before i did this.
