My 1st generation ipod touch won't update. Right now my itunes says I have version 2.2.1 and when I click check for updates, it says I have the newest version. My itunes is updated to the current version, so I don't think that could be part of the problem. My friend has the same ipod as me and his ipod is updated to 3.1.3. Why won't mine update to this version?? Thank you in advance for your help.
