Updating Applications
Whenever you access the App Store, it checks for updates to applications you’ve
installed. 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 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 iPhone 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 dierent iTunes Store account,
you’re prompted for that account’s ID and password in order to download the update.
Syncing Purchased Applications
iTunes automatically syncs applications you’ve downloaded or purchased on iPhone
to your iTunes library when you connect iPhone to your computer. This lets you access
the downloads on your computer and provides a backup if you delete applications
from iPhone.
Downloaded applications are backed up the next time you sync with iTunes.
Afterwards, only application data is backed up when you sync with iTunes.
Applications are synced to the Applications list in your iTunes library. iTunes creates
the list if it doesn’t exist.
