Q: i pod has a version 2.2.1 and says it needs to update but it will not update

The iPod your daughter has would either be a first or second generation unit, neither of which will run iOS 4.3 or later. There are still apps available that will work on iOS 4.2.1, which if the unit is second-generation it will run, or even iOS 3.1.3, the last version of iOS a first-gen iPod touch can run (the upgrade for that unit is not free, but is still available the last I heard). You can determine which model the iPod is via this information:

If she really wants to run apps that require iOS 4.3 or later, then she'll need a newer iPod touch.

Then iOS 3.1.3 is the highest it can go. The upgrade should still be available here if she wants it:

Purchasing iOS 3.1 Software Update for iPod touch (1st generation)

but there are very few apps available that will still run, and very very few that anyone really still wants unless your daughter is quite young. If she is, or otherwise just wants to look, you or she can check out these web sites:

Other posts here may provide other tips on how to look for compatible apps.

You're very welcome. Cheers.
