Okay so i had the 3.0 beta 4 and everyone knows that you need itunes 8.2 to install beta 5; so I put it into dfu mode and tried to install beta 2, and it worked. I tried to do this so i could open up itunes 8.1 and install beta 5 from there. Now its stuck in DFU mode and when i plug it into itunes 8.1 an error message comes up saying cannot be synced and i can't get to the summary page to restore it. Someone please help, my ipod is useless at this point and I have no clue how to fix this. Someone, anyone?
