摘要： A method, apparatus and system for reducing download of redundant attachments to a communication device from a server is provided. An identifier of attachment to a message, for transmission from the server to the communication device, is compared with identifiers of attachments already stored in a memory at the communication device. The communication device is caused to retrieve a copy of the attachment from the memory if a match is found between the identifier and the identifiers of attachments already stored in the memory.

摘要： Displaying a map in a mobile communication device. Geographic coordinate information for a location of an address in a contact is determined. A user context for the mobile communications device is also determined. A request for a table of contents of available map data without the map data with the geographic coordinate information of the location as input is sent and the table of contents of available map data is received. A subset of map data comprising less data than is listed in the table of contents for the location corresponding to the geographic coordinate information is selected based on the table of contents of available map data and the user context. The subset of the map data is requested and the map with the subset of the map data is caused to be rendered in the display.
