I tried to jailbreak but no luck. I was following this tutorial by Willdta http://www.youtube.com/watch?v=23qTFceH0jI Everything went smoothly until I had to use the 'custom restore.ipsw' which was downloadable in the description. I keep on getting error 21 from itunes. I have looked up the fix to this error on the internet but with no solid answers as to the work around. I am using a mac os x on 10.5.6. I have installed the 'Install_IOUSBFamily_kext_10_5_5.zip' which fixes the problem with getting the ipod into dfu mode for 10.5.6. I don't think that was ever the problem though because I could always get into DFU mode. My only query is when Final Snow is installing itself, it asks me to disconnect then reconnect the ipod and this should show a white screen. But in reality it doesn't do anything, the screen with the itunes and the usb cable just sits there the same as before. I can still restore to the original firmware which I have done for now. But my question is, why does itunes give me error 21?
