Apple iPod touch iOS 2.2 - Manual (Page 109)

Appendix A Troubleshooting 109
Email Can’t Be Delivered (Port 25 Timed Out)
You may need to change the port setting on an outgoing mail server for one of your
email accounts. For information, go to www.apple.com/support/ipodtouch and search
for “I can receive email on iPod touch but can’t send it.”
GAL Contacts Don’t Appear
Make sure iPod touch is joined to a Wi-Fi network that is connected to the Internet.
Check your Microsoft Exchange settings to make sure you’re on the right server. In
Settings, tap “Mail, Contacts, Calendars” and choose an account to display its settings.
If you’re trying to search for GAL contacts in Contacts, tap Groups and tap Directories
at the bottom of the list.
Backing Up iPod touch
iTunes creates backups of settings, downloaded applications and data, and other
information on iPod touch. You can use a backup to restore these items to your
iPod touch after a software restore or to transfer the information to another
iPod touch.
Backing up iPod touch or restoring from a backup is not the same as syncing content
and other items (such as music, podcasts, ringtones, photos, videos, and applications
that you download via iTunes) with your iTunes library. Backups include settings,
downloaded applications and data, and other information that resides on iPod touch.
You can restore these items from a backup using iTunes, but you may also have to sync
your iTunes library content again.
Applications downloaded from the App Store are backed up the next time you sync
with iTunes. Afterwards, only application data is backed up when you sync with iTunes.
Creating Backups
Backups can be created in the following ways:
Once iPod touch has been configured to sync with a particular computer, iTunes Â
automatically makes a backup of iPod touch on that computer when you sync.
iTunes won’t automatically back up an iPod touch that is not configured to sync
with that computer. If you have configured iPod touch to automatically sync with
iTunes on a specific computer, iTunes will back up iPod touch every time you
connect it to that computer. Automatic syncing is turned on by default. iTunes only
makes one backup each time you connect, even if you sync multiple times before
disconnecting.
If you choose to update the software on iPod touch, iTunes will back up iPod touch
Â
automatically, even if it is not configured to sync with iTunes on that computer.
If you choose to restore the software on iPod touch, iTunes asks if you want to back
Â
up iPod touch before restoring.
