Getting UP.Phone preferences

The UP.Phone provides a built-in user preferences service, which maintains user preferences. The user preferences service allows your service to access user preferences. It provides the following URLs for this purpose.

Currently, all UP.Phones provide the following preference:

Individual phone models may provide additional preferences which you can retrieve. For a list of device-specific preferences, consult the phone manufacturer.

For example, the following WML deck retrieves the user's time zone preference and displays it:

<!-- http://foo.com/time.cgi -->
<wml>
<card>
<onevent type="onenterforward">
 <go href="uplink_svc.cgi?svc=pref&amp;nexturl=time.cgi#tz"/>
</onevent>
</card>

<card id="tz">
  <p>
    Your time zone preference is:<br/>
    $(TZ)

  </p>
</card>
</wml>

Figure  3-3.     Deck that displays the user's time zone preference

Of course, you can also pass the time zone preference back to your service with a query string. The clock.cgi example provided with the UP.SDK demonstrates how to use the time zone preference to calculate the current time.
