I just updated my iPod Touch to iOS 5.1. During the process, iTunes downloaded a 750MB file:
~/Library/iTunes/iPod Software Updates/iPod4,1_5.1_9B176_Restore.ipsw. I have no use for this file anymore, and it's just using up my limited disk space, so I want to get rid of it.
Will this file ever get deleted automatically, or will it stay there indefinitely?
Is there any GUI command in iTunes that will delete all such files?
Is it safe to manually delete this file?
If I manually delete it, will I be able to easily download it again if I ever do need it?
Update: Ipsw files now appear in
~/Library/MobileDevice/Software Images, and they take up 1+ GB.
