Apple iPod touch iOS 4.3 - Manual (Page 157)

When you’re trying to access the Internet, by using Safari or Mail for example, and
you aren’t in range of a Wi-Fi network you‘ve previously used, this option tells
iPod touch to look for another network. iPod touch displays a list of all available Wi-Fi
networks that you can choose from. (Networks that require a password appear with a
lock icon.) If “Ask to Join Networks” is turned off, you must manually join a network
to connect to the Internet when a previously used network isn’t available.
Forget a network, so iPod touch doesn’t join it: Choose Wi-Fi and tap next to a
network you’ve joined before. Then tap “Forget this Network.”
Join a closed Wi-Fi network: To join a Wi-Fi network that isn’t shown in the list of
scanned networks, choose Wi-Fi > Other, then enter the network name. If the network
requires a password, tap Security, tap the type of security the network uses, and enter
the password.
You must already know the network name, password, and security type to connect to
a closed network.
Some Wi-Fi networks may require you to enter or adjust additional settings, such as a
client ID or static IP address. Ask the network administrator which settings to use.
Adjust settings for connecting to a Wi-Fi network: Choose Wi-Fi, then tap next to
a network.
VPN
This setting appears when you have VPN configured on iPod touch, allowing you to
turn VPN on or off. See “Network” on page 159.
Notifications
This setting appears when you open an app (such as Game Center) that uses the
Apple Push Notification service.
Push notifications alert you to new information, even when the app isn’t running.
Notifications vary by app, but may include text or sound alerts, and a numbered badge
on the app icon on the Home screen.
You can turn notifications off if you don’t want to be notified, or if you want to
conserve battery life.
Turn all notifications on or off: Tap Notifications, then turn notifications on or off.
Turn sounds, alerts, or badges on or off for an app: Tap Notifications, choose an app
from the list, then choose the types of notification you want to turn on or off.
