Abstract: A method of sharing data accessible by a server, with a portable electronic device of a first entity includes receiving permission at the server to share with the first entity, data associated with a second entity, the data for use with an application. The server retrieves the data associated with the second entity and transmits the data from the server to the portable electronic device of the first entity. The data associated with the second entity is received at the portable electronic device of the first entity and stored in association with a second entity identifier, thereby distinguishing the data from other data for use with the application.

Abstract: A method of managing databases at an electronic device, associated with respective ones of a first PIM service account and a second PIM service account. The method includes: receiving representative data of records at a server associated with the second PIM service account and obtaining data representative of records already present at the electronic device; comparing the data representative of the records at the server with the data representative of records already present at the electronic device; and determining with which of two of the databases ones of the records, at the server, for which representative data is received are associated, based on whether each of the records, at the server, for which representative data is received is already present in one of the two of the databases.
