Preferences are stored by Creator/type, that 4 letter unique value that you
registered for your application.
if you swiped sample code from the address book application most likely it's
using it's creator when you save them on app exit.
PrefSetAppPreferences(appFileCreator, appPrefID, appPrefVersionNum,
&gPrefs, sizeof(PreferenceType), true);
appFileCreator is defined somewhere and probably matches Addressbook instead
of your unique value (which you'll register before you release right ?)
