How to Sync and Arrange Apps for an iPod Touch
Click the Apps tab.
The Apps sync options page appears. By default, all apps that work on the iPod touch are automatically synced.
From the list box on the left, click the Install or Remove button for each app that you want to install or remove from the iPod touch.
You can scroll the list box to see all your apps — and you can click the Sort button at the top to toggle sorting the list by Name, Kind, Category, Date, or Size. For example, the illustration shows switching from Sort by Kind to Sort by Category.
