Problem updating iPod Touch to iOS 5 Using iTunes to upgrade the OS on a 4th generation iPod Touch, the update downloads but when it attempts to install it the process fails with the following message:


  The iPod "iPod Touch (4G)" could not be restored. An internal error occurred.


Any ideas what might cause this and how to avoid it?
It is server overload. Either keep trying or wait till the traffic dies down a little.
