Delete an account from iPod touch: Choose “Mail, Contacts, Calendars,” choose an
account, then scroll down and tap Delete Account.
Deleting an account means you can no longer access the account with your
iPod touch. All email and the contacts, calendar, and bookmark information synced
with the account are removed from iPod touch. However, deleting an account doesn’t
remove the account or its associated information from your computer.
Fetch New Data
This setting lets you turn Push on or off for MobileMe, Microsoft Exchange, Yahoo!
Mail, and any other push accounts you’ve configured on iPod touch. Push accounts
automatically deliver new information to iPod touch when 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 is 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 frequently.
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 in the Fetch New Data screen
overrides individual account settings.
Mail
The 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.
