This article explains how to rearrange the app icons on the Home screen of an iPod nano 6th and 7th generation.
Fortunately, both the 6th generation iPod nano and the 7th generation iPod nano let you rearrange the app icons to your liking. Here's what to do:
No. Only the 6th and 7th generation models have app icons. All other versions use menus, the order of which cannot be changed.
No. Unlike the iPhone or iPad, apps that are built into the iPod nano must remain there. Apple does not give you a way to remove them.
