iPod Reset Utility 1.0

It's not a security update, but if you have an iPod Shuffle and need to restore it back to factory settings, this may interest you. iPod Reset Utility will restore your Shuffle back to factory settings when you aren't able to use the restore feature in iTunes. I would follow the iPod 5 R's before using the reset utility, since restoring your iPod will erase your music from the Shuffle.

iPod Rest Utility 1.0 download for Windows and Mac. Installation info and use can be found here.
