Apple iPod touch iOS 2.2 - Manual (Page 50)

Downloading Applications
When you find an application you want in the App Store, you can purchase and
download it to iPod touch. If the application is free, you can download it without
charge after providing your iTunes account information.
Once you download an application, it is immediately installed on iPod touch.
Purchase and download an application:
1 Tap the price (or tap Free), then tap Buy Now.
If you were signed in to your iTunes Store account in iTunes the last time you synced
iPod touch, you don’t have to enter your account ID. Otherwise, you are prompted to
enter your account ID.
2 Enter your password and tap OK.
Downloads for purchase are charged to your iTunes Store account. For additional
downloads made within the next fifteen minutes, you don’t have to enter your
password again.
See the status of downloading applications: After you begin downloading an
application, its icon appears on your Home screen and shows the status of the
download and installation.
While downloading purchases, it’s okay to turn off iPod touch or leave the area of your
network connection. iPod touch starts the download again the next time iPod touch
joins a network with an Internet connection.
Deleting App Store Applications
You can delete applications you’ve installed from the App Store. If you delete an
application, data associated with the application will no longer be available to
iPod touch, even if you reinstall the application.
You can reinstall any application and any associated data from your iTunes library
as long as you backed up the application by syncing to your computer. If you try to
delete an application that hasn’t been backed up to your computer, an alert appears.
Delete an App Store application:
1 Touch and hold any application icon on the Home screen until the icons start to
wiggle.
2 Tap the “x” in the corner of the application you want to delete.
3 Tap Delete, then press the Home button to save your arrangement.
