Stacey made a one letter error setting up her iPod and she can't download any music on it. She went to the Apple store and the Genius punted and said to call Apple Care. Leo says that the music industry insisted on using a single iTunes account authorized to an Apple account. Stacey should be able to authorize the iPod using her Apple account. If she resets the iPod through iTunes, she should be able to set it up as a new device.
Apple has had a lot of security issues as of late, one of them relating to its Apple ID "forgot password" system. It was possible for anyone to gain access to another user's account simply by knowing their email address and birthday. This lead to Apple taking down iforgot.apple.com until just recently.
