Apple iPod touch iOS 2.0 - Manual (Page 12)

Push Accounts
MobileMe, Microsoft Exchange, and Yahoo! Mail are known as “push” accounts. When
new information is available, such as the arrival of an email message, the information
is automatically delivered (pushed) to your computer or to iPod touch. (In contrast,
“fetch” services require your email software to periodically check with your service
provider to see if new messages have arrived, and then request them to be delivered.)
MobileMe and Exchange also sync your contacts, calendars, and bookmarks (MobileMe
only) in the same way. For example, if you add a contact to the address book on your
computer, the new contact is automatically pushed to iPod touch as well as to any
other computer or device configured with the service.
Synced information is transferred automatically over your wireless connection; you
don’t need to connect iPod touch to your computer to sync. iPod touch can receive
pushed data over a Wi-Fi connection only when iPod touch is awake (the screen is on,
or iPod touch is connected to your computer or a power adapter).
Installing Configuration Profiles
If you’re in an enterprise environment, you may be able to set up accounts and
other items on iPod touch by installing a configuration profile. Configuration profiles
provide a way for system administrators to quickly set up your iPod touch to work
with the information systems at your company, school, or organization. For example, a
configuration profile might set up your iPod touch to access the Microsoft Exchange
servers at work, enabling iPod touch to access your Exchange email, calendars, and
contacts.
Configuration profiles can configure multiple settings on iPod touch all at once. For
example, a configuration profile can set up your Microsoft Exchange account, VPN
account, and certificates for secure access to your company’s network and information.
A configuration profile may turn on the Passcode Lock, requiring you to create and
enter a passcode for using iPod touch.
Your system administrator may distribute configuration profiles by email or by putting
them on a secure webpage.
