HOW TO UPGRADE FROM IOS 4.3.4 (OR EARLIER)
TO iOS 5

If you have an iPhone or iPad that currently has iOS 4.3.4 (or an earlier version)
installed, follow the directions in this section to download and install the iOS 5
operating system onto your device.

FIND OUT WHICH VERSION OF iOS YOUR DEVICE USES

To determine which version of the iOS operating system your device currently
has installed, from the Home Screen, tap on the Settings app, and then tap on the
General option. Next, tap on the About option, found under the General heading,
and look at the Version information. Figure 1.1 shows this on an iPhone 4 that is
currently running iOS 4.3.4.

From the Settings app on your device, you can easily determine which version of iOS it’s running.

TIP To upgrade from iOS 4.3.4 (or earlier) to iOS 5, your primary computer
must be running the most current version of iTunes (version 10.5 or later). From
the iTunes pull-down menu, click the Check for Updates option to ensure you’re
running the latest version of this software on your Mac or PC. If you’re informed
that a more up-to-date version of the iTunes software is available, download and
install it before upgrading your mobile device to iOS 5.

If you need to download and install iTunes for the first time on your PC or Mac,
visit www.apple.com/itunes/download.

AVOIDING iTUNES CONFUSION

You have an iTunes app on your computer and you have an iTunes app on your
Apple mobile device, but these apps have different purposes. The iTunes app on
your computer is for syncing and backing up content, managing applications, listening
to or viewing your purchased content (such as movies, music, or podcasts)
on your computer, and so on.

The iTunes app on your mobile device is used to purchase and download content
directly to that device, as well as to access Apple’s Ping service from the device.
Other applications on your mobile device enable you to play your purchased content.
For example, you can use the Music app to listen to your downloaded music.

HOW TO UPGRADE TO iOS 5 USING iTUNES

After the latest version of iTunes (version 10.5 or later) is running on your PC or
Mac, use the iTunes sync procedure to create a current backup for your iPhone or
iPad before starting the iOS 5 download and install process. To do this, iTunes must
be running on your primary computer, and your mobile device should be connected
to your computer via the white USB cable that came with your iOS device.
If you’re using an optional dock, your iPhone or iPad should be inserted into the
dock, and the dock should be connected to your primary computer (or a USB hub
that’s connected to your primary computer) via the supplied USB cable.
From this point forward, your primary computer must be connected to the Internet
to continue with the iOS 5 upgrade procedure. After completing the backup process,
click the Summary tab for your iPhone, iPad, or iPod touch that’s displayed at
the top of the iTunes screen (on your primary computer). In the Version box, click
the Check for Update icon.

iTunes will determine what the most recent version of iOS 5 is. If your iOS device is
running an older version of the operating system, a message appears stating that

you should download and install the latest version of the iOS operating system,
which will be iOS 5.0 or later.

Follow the onscreen prompts on your primary computer to begin downloading
iOS 5. During this procedure, do not disconnect your iPhone, iPad, or iPod touch.
Depending on the speed of your Internet connection, the iOS 5 download process
could take a while, so be patient.

When iOS 5 has been downloaded, it will automatically be transferred to your
iPhone or iPad and installed. Again, this process could take up to 30 minutes, so be
patient and do not disconnect your iOS device from the primary computer during
this process or attempt to use the device.

After iOS 5 is installed on your Apple mobile device, it will reset. At this point, it will
be necessary to configure iOS 5 on your device, and then restore your saved apps
and data.
