automatically turn off Wi-Fi after a specified timeout period.
1. Tap Start > Settings > Connections > Wi-Fi and then tap the Wireless
Networks button.

3.
Select the timeout period for automatically turning off Wi-Fi when your
phone is not connected to any wireless network.
GPRS
Use GPRS (or EDGE, if available) to connect to the Internet and to send and receive
email on your phone. You will need a data plan to use your mobile operator's GPRS
network. Check with your mobile operator to find out about GPRS rates.
If you completed the Connection Setup process for auto-configuring the data
connection the first time you turned on your phone, your phone is ready to use
GPRS services. Do not change the connection settings as this may cause services to
stop working. If you need to add another GPRS connection on your phone, contact
your mobile operator.
Note
If you did not complete the auto-configuration process before, follow the instructions
in "Using Connection Setup" in Chapter 1 to configure the data connection for your
phone.
