preferences without a preference screen?
<p>I am saving a number of preferences which are defined in an xml Preference Screen file.  Included are a few names and phone numbers.   I have managed to connect the contacts list to the preference screen so I only need to show on the preference list one entry and then I can recover the name and number from the contacts.   However if both name and number are not shown on the preference screen as seperate items then I do not seem to able to save the missing item. </p>

<p>Are Preferences only available if they are part of a displayed screen?</p>
