9. How do I start my 6-month complimentary access period?
From your PSP, upgrade to the latest system firmware version 3.3 or above, then bring your PSP® system to a location that provides a T-Mobile HotSpot and follow these easy steps:
1. Select Settings, Network Settings.
2. Select [Infrastructure Mode], [New Connection], [Use Wireless Hotspot].
3. Select the T-Mobile HotSpot icon.
* For an existing T-Mobile HotSpot account: select [Enter User Credentials], enter your user ID and password, and then press the right button.
or
* For a new account: select [Use Promotional Access] to sign up for a complimentary 6-month T-Mobile HotSpot account. (To qualify for this promotional access, you must authenticate your PSP® system to the T-Mobile HotSpot network before March 28, 2008.)
4. Check the contents of the settings list and save the settings.
5. Perform a connection test. If you select [Test Connection], the system will connect to the selected access point.
6. Confirm the connection test results. If the connection is successful, information about the network displays.
