When I upgraded my 32g iPod Touch 4th Generation to IOS 5 the amount of storage used listed in "Other(Yellow)" on my iPod went from just under 2g to 8.2g. When we downloaded IOS 5 to my husbands 32g iPhone 4 it barely changed. My iPod is now suddenly down to less than 3g of storage to spare and the amount of storage used in Other is almost as much as in my Music. Is this normal or is there something wrong with how it downloaded onto my iPod. It seems excessive. Thanks in advance for your help/input.
The problem was due to some files being corrupted during the update. To resolve, you need to restore the iPod. First from backup and if problem persists, restore to factory defaults/new iPod. Also, disable auto-syncing upon connecting the iPod (iTunes>Preferences>Devices) otherwise iTunes will backup the iod with the problem and the problm will be in that backup.
