Removing all Instances of Multi-Valued User Preferences

Each set_userprefs command removes only one instance of a multi-valued preference.

Workaround: To remove all instances of a multi-valued user preference, you must issue one set_userpref command per instance.

For example: Perform a get_userprefs to list all of the user preferences. If there are multiple values for a preference, such as icsSubscribed , then you must issue one set_userprefs command to delete the preference for each of the values listed.
