Abstract: A method comprises receiving, via a user interface of a user terminal, an indication of a user selection of a contact identifier, identifying, from plural event information items stored in at least one memory, an event information item which is associated with the selected contact, wherein each of the plural event information items has a timestamp associated therewith, and causing a graphical chronology to be displayed on a display (14) of the user terminal, wherein the graphical chronology comprises plural sub-regions (50-1-50-3) each relating to a different time interval, wherein the graphical chronology includes a graphical representation of the identified event information item (53, 55), the graphical representation being located in a one of the sub-regions (50-1-50-3) based on a comparison of the timestamp associated with the identified event information item and the time interval to which the sub-region (50-1-50-3) relates.

Abstract: A method comprises determining when a first portable device and a second portable device have been at a same current location for longer than a predetermined duration, and subsequent to determining that the first and second portable devices, have been at the same current location for longer than the predetermined duration, creating a database entry associated with the first portable device, the database entry including information identifying the second portable device.
