摘要：
A method for determining latitude and longitude coordinates for geographic addresses input into an address book on a mobile device is provided. For each geographic address received for storing in a contact record, latitude and longitude coordinates are automatically determined and associated with the geographic address in a database of contact records. In some embodiments, for each geographic address to be input, the method first searches existing contact records for the geographic address and if the latitude and longitude coordinates for the geographic address are in an existing contact record, the contact record for the contact is cross-referenced to the existing record for accessing the latitude and longitude coordinates.
