Novel apparatus and methods for filtering data packets by providing non-user configurable authorization data. The backlight includes: a light emitting diode substrate on which light emitting diodes are mounted; a reflection sheet that is provided on the light emitting diode substrate and has holes formed therein, each of the light emitting diodes being provided inside each of the holes; and lenses provided on the light emitting diodes, for diffusing light from the light emitting diodes. An inlet passage through which a potting material is poured, outlet passages through which the potting material runs out, base portions which are inscribed in the inside wall of the lead-wire-fixed portion are formed in the upper portion of the lead-wire-fixing attachment. Additional components include a keyboard or write pad mounted on the pivoting cover or on a separate pivoting mount near the center bag front, a display prop which braces the display in various angular positions and side pockets fitted for peripherals. The base station selectively transmits an acknowledgment message based on in part an availability of the determined uplink scrambling code. The steps include identifying a group of recipients with whom to share the voice mail message, creating a user profile which includes voice mail preferences of a subscriber and the group of recipients, the preferences including an indication as whether to share the voice mail message with the group of recipients and distributing the voice mail message based on the preferences.
