Updating Apps
Whenever you access the App Store, it checks for updates to apps you’ve installed.
The App Store also automatically checks for updates every week. The App Store icon
shows the total number of app updates available.
If an update is available and you access the App Store, the Updates screen appears
immediately. App updates are downloaded and automatically installed when you
choose to update them.
App upgrades are new releases that can be purchased or downloaded through the
App Store on iPod touch or the iTunes Store on your computer.
Update an app:
1 At the bottom of the screen, tap Updates.
2 Tap an app to see more information about the update.
3 Tap Update.
Update all apps: At the bottom of the screen, tap Updates, then tap Update All.
If you try to update an app purchased from a dierent Apple account, you’re asked for
that account ID and password in order to download the update.
Syncing Purchased Apps
When you connect iPod touch to your computer, iTunes syncs apps you download or
purchase on iPod touch to your iTunes library. This lets you access the downloads on
your computer and provides a backup if you delete apps from iPod touch.
Downloaded apps are backed up the next time you sync with iTunes. Afterwards, only
app data is backed up when you sync with iTunes.
Apps are synced to the Apps list in your iTunes library. iTunes creates the list if it
doesn’t exist.
