About Syncing
Syncing copies information from your computer or online account to iPhone, then
keeps the information in sync by copying changes made in one location to the other.
You use iTunes on your computer to sync contacts, calendars, and other information;
iOS apps; photos and videos; and music and other iTunes content. By default, syncing
occurs whenever you connect iPhone to your computer.

MobileMe, Microsoft Exchange, Google, Yahoo!, and others. Your information on those
services is synced over the air.
Syncing Accounts
MobileMe, Microsoft Exchange, Google, Yahoo!, and other online service providers
sync information—which might include contacts, calendars, browser bookmarks,
and notes—wirelessly over the air, so you don’t have to connect iPhone to your
computer. The wireless Internet connection can be via your cellular network or your
local Wi-Fi network.
Some service providers—including MobileMe and Microsoft Exchange—push
information updates. This means that syncing happens whenever any information is
changed. The Push setting in Fetch New Data must be turned on (it’s on by default).
Other providers sync by periodically “fetching” changes that have occurred. Use the
Fetch setting to determine how frequently this happens. See “Fetch New Data” on
page 203.
For information about setting up accounts on iPhone, see “Adding Mail, Contacts, and
Calendar Accounts” on page 25.
