Hi all. I tried updating my iPod Touch to 2.2 from 2.0 through Xcode. It did it almost and and the device disappeared from the device list in Xcode > Organizer Now the device is showing Cable & iTunes in display. So i tried connecting to iTunes, But both iTunes and Xcode is throwing Error "Unknown Error" Earlier i tried installing OS2.0 through Xcode without any difficulty. And it asked me to activate through iTunes. I did and everything worked fine then... Please Help.. I am not connected to internet. Is it mandatory to have network connection (connect to UpdateServer) so as to update / activate OS in TOuch ?
