A group communication method for a wireless information device, in which the method comprises the step of using an application independent object which defines or references members of a group in a way that enables communication to take place between two or more members of the group. The group object defines solely the identities of members of a group: as such, it is application (and hence also content) independent. This means that a group created in one application (e.g. a diary/agenda application could use that same group as the recipient list for an invitation to a meeting); a voice application could use that same group to allow a voice call to be conferenced across to all group members. Similarly, data specifically created for one group and in one application can be re-used in a different application and the data viewed appropriately for that different application.
