Updating Applications
Whenever you access the App Store, it checks for updates to applications you’ve
installed. By default, the App Store also automatically checks for updates every week.
The App Store icon shows the total number of application updates available.
If an update is available and you access the App Store, the Updates screen appears
immediately. Application updates are free and are downloaded and automatically
installed when you choose to update them. Application 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 application:
1 At the bottom of the screen, tap Updates.
2 Tap an application to see more information about the update.
3 Tap Update.
Update all applications: At the bottom of the screen, tap Updates, then tap Update
All.
If you try to update an application purchased from a different iTunes Store account,
you are prompted for that account’s ID and password in order to download the
update.
