							Deleting 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 iPhone, 
unless you reinstall the application and restore its data from a backup.
You can reinstall an application and restore its data as long as you backed up iPhone 
with iTunes on your computer. (If you try to delete an application that hasn’t been 
backed up to your computer, an alert appears.) To retrieve the application data, 
you must restore iPhone from a backup containing the data. See “Restoring from a 
Backup
” on page 203 .
Delete an App Store application:
 1  Touch and hold any application icon on the Home screen until the icons start to 
wiggle.
 2 Tap  in the corner of the application you want to delete.
 3 Tap Delete, then press the Home  button to save your arrangement.
When you delete an application, its data is no longer accessible via the iPhone user 
interface, but it isn’t erased from your iPhone. For information about erasing all 
content and settings, see “Erase All Content and Settings” in iPhone settings.  
See “Resetting iPhone
” on page 149 .
Writing Reviews
You can write and submit your own application reviews directly on iPhone.
Write a review:
 1 Tap Ratings near the bottom of the Info screen.
 2 On the Reviews screen, tap “Write a Review.”
 3 Select the number of stars (1–5) for your rating of the application, and enter your

reviews before, the nickname field is already filled in. Otherwise, you’re asked to create 
a reviewer nickname.
 4 Tap Send.
You must be signed in to your iTunes Store account and have purchased or 
downloaded the item in order to submit reviews.

							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 different 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.

							Compass
22
Getting Compass Readings
The built-in compass (iPhone 3GS only) shows which direction you’re facing, along 
with the geographical coordinates of your current location. You can choose magnetic 
north, or have Compass adjust the declination to show true north.
Important:  The accuracy of digital compass headings may be negatively affected by 
magnetic or other environmental interference, including interference caused by the 
close proximity of the magnets contained in the iPhone earbuds. The digital compass 
should only be used for basic navigation assistance and should not be solely relied on 
to determine precise locations, proximity, distance, or direction.
The compass needs to be calibrated the first time you use it, and may need to be 
calibrated occasionally after that. iPhone alerts you whenever calibration is needed.
Calibrate iPhone:   Wave iPhone in a figure eight. You may be asked to move away 
from a source of interference.

							See which way you’re facing:  Hold iPhone level to the ground. The compass needle

The coordinates of your current location are displayed at the bottom of the screen.
Switch between true north and magnetic north:   Tap  and tap the setting  
you want.
Compass and Maps
The  icon at the bottom of the Compass screen lets you find your current location 
in Maps. Maps also takes advantage of the built-in compass to show which way you’re 
facing.
See your current location in Maps:   Tap . Maps opens and indicates your current 
location with a blue marker.
