Apple iPod touch iOS 4.3 - Manual (Page 19)

Disconnecting iPod touch from Your Computer
You can disconnect iPod touch from your computer at any time. However, if you
disconnect it while a sync is in progress, some data may not get synced until the next
time you connect iPod touch to your computer.
When iPod touch is syncing with your computer, iPod touch shows “Sync in Progress.”
If you disconnect iPod touch before it finishes syncing, some data may not get
transferred. When the sync is complete, iTunes shows “iPod touch sync is complete.”
Cancel a sync: Drag the slider on iPod touch.
Connecting to the Internet
iPod touch connects to the Internet via Wi-Fi networks. iPod touch can join AirPort
and other Wi-Fi networks at home, at work, or at Wi-Fi hotspots around the world.
When joined to a Wi-Fi network that’s connected to the Internet, iPod touch accesses
the Internet automatically whenever you use Mail, Safari, YouTube, FaceTime, Game
Center, Stocks, Maps, Weather, the App Store, or the iTunes Store.
Joining a Wi-Fi Network
The Wi-Fi settings let you turn on Wi-Fi and join Wi-Fi networks.
Turn on Wi-Fi: Choose Settings > Wi-Fi and turn Wi-Fi on.
Join a Wi-Fi network: Choose Settings > Wi-Fi, wait a moment as iPod touch detects
networks in range, then select a network (fees may apply to join some Wi-Fi networks).
If necessary, enter a password and tap Join (networks that require a password appear
with a lock icon).
Once you join a Wi-Fi network manually, iPod touch automatically connects to it
whenever the network is in range. If more than one previously used network is in
range, iPod touch joins the one last used.
When iPod touch is connected to a Wi-Fi network, the Wi-Fi icon in the status bar
at the top of the screen shows the connection strength. The more bars you see, the
stronger the connection.
For information about configuring Wi-Fi settings, see “Wi-Fi” on page 156.
VPN Access
VPN (virtual private network) provides secure access over the Internet to private
networks, such as the network at your company or school. Use Network settings to
configure and turn on VPN. See “Network” on page 159.
