The apparatus adds said second identified item to said list of selected items if said second item is not on said list.

Abstract: A communications device capable of communicating via any one of a number of communication modes comprises a mode comparator configured to determine which of the available modes is likely to be most appropriate for selection when initiating communication with a destination call party based at least in part on availability status data representative of a state of availability of the destination call party. The device displays the mode as a suggestion for selection by the user together with an ordered list of available communication modes for use in contacting a particular party, the list being ordered according to the likelihood of communication being successful.

Abstract: A computing device includes a communication port, memory resources, and one or more processors. The one or more processors are configured to combine with the memory resources to operate one or more of the plurality of modules. The plurality of modules are operative in order to handle exchange of communications with a primary computer over the communication port.
