Apple iPod touch iOS 4.3 - Manual (Page 171)

Fetch New Data
This setting lets you turn Push on or off for MobileMe, Microsoft Exchange, Yahoo!, and
any other push accounts on iPod touch. Push accounts deliver new information to
iPod touch whenever new information appears on the server (some delays may occur).
To fetch or sync pushed data, iPod touch must join a Wi-Fi network that’s connected to
the Internet. You might want to turn Push off to suspend delivery of email and other
information, or to conserve battery life.
When Push is off, and with accounts that don’t support push, data can still be
fetched—that is, iPod touch can check with the server and see if new information is
available. Use the Fetch New Data setting to determine how often data is requested.
For optimal battery life, don’t fetch too often.
Turn Push on: Choose “Mail, Contacts, Calendars” > Fetch New Data, then tap to turn
Push on.
Set the interval to fetch data: Choose “Mail, Contacts, Calendars” > Fetch New Data,
then choose how often you want to fetch data for all accounts.
To conserve battery life, fetch less frequently.
Setting Push to OFF (or setting Fetch to Manually on the Fetch New Data screen)
overrides individual account settings.
Mail
Mail settings, except where noted, apply to all accounts you’ve set up on iPod touch.
To turn alerts sounds for new or sent mail on or off, use the General > Sounds settings.
Set the number of messages shown on iPod touch: Choose “Mail, Contacts,
Calendars” > Show, then choose a setting.
Choose to see the most recent 25, 50, 75, 100, or 200 messages. To download
additional messages when you’re in Mail, scroll to the bottom of your inbox and tap
Load More Messages.
Note: For Microsoft Exchange accounts, choose “Mail, Contacts, Calendars” and choose
the Exchange account. Tap “Mail days to sync” and choose the number of days of mail
you want to sync with the server.
Set how many lines of each message are shown in the message list: Choose “Mail,
Contacts, Calendars” > Preview, then choose a setting.
You can choose to see up to five lines of each message. That way, you can scan a list
of messages in a mailbox and get an idea of what each message is about.
Set a minimum font size for messages: Choose “Mail, Contacts, Calendars” >
Minimum Font Size, then choose Small, Medium, Large, Extra Large, or Giant.
Set whether iPod touch shows To and Cc labels in message lists: Choose “Mail,
Contacts, Calendars,” then turn Show To/Cc Label on or off.
