Abstract
A mobile electronic communication device includes a processor unit, a transceiver, a keypad and a light unit. Each key of the keypad is associated with a contact of a contact list. The light unit can perform light functions to notify a user of the reception and/or status of messages received via the transceiver. The light functions include providing an indication of the age of a received message that was sent by a contact in the contacts list. The age of the message is indicated by a modulation of the illuminating light. In one embodiment, the age of a message is indicated as one of a set of predetermined age ranges, with each age range being represented by a unique color.
