1. A method comprising: receiving, from a wireless communication device, location information indicating a current map segment of a plurality of map segments simultaneously displayed on the wireless communication device to form a map displayed on the wireless communication device, the current map segment including a device location of the wireless communication device on the map; andidentifying pushpin data based on the current map segment, the pushpin data indicating a pushpin location on the map and meeting a criteria received from the wireless communication device; andsending the pushpin data to the wireless communication device. 2. The method of claim 1, wherein the location information comprises a current map segment index identifying the current map segment. 3. The method of claim 1, wherein the pushpin data indicates a plurality of pushpin locations on the map. 4. A method comprising: displaying a map on a wireless communication device, the map formed by a plurality of rectangular map segments simultaneously displayed on the wireless communication device;sending, to a server, location information indicating a current map segment of the plurality of map segments, the current map segment including a device location of the wireless communication device on the map;sending, to the server, criteria for identifying at least one pushpin location;receiving, from the server, pushpin data indicating the at least one pushpin location on the map and meeting the criteria; anddisplaying the at least one pushpin location on the map. 5. The method of claim 4, wherein the pushpin data indicates a plurality of pushpin locations, the method further comprising: comparing geographical pushpin indexes to map segment identifiers of the map segments; anddisplaying only pushpin locations on the map that have geographical pushpin indexes corresponding to the map segment identifiers. 6. The method of claim 5, further comprising: calculating the geographical pushpin indexes from the pushpin data. 7. The method of claim 4, further comprising: downloading a non-cached map segment including one or more of the at least one pushpin location. 8. A method comprising: sending first pushpin data to a wireless communication device based on a criteria and a geographical region associated with the wireless communication device, the pushpin data representing a first location on a map displayed on the wireless communication device and formed by a plurality of map segments simultaneously displayed on the wireless communication device;receiving, from the wireless communication device, updated location information indicating a current map segment of the plurality of map segments, the current map segment including a device location of the wireless communication device on the map; andsending second pushpin data to the wireless communication device based on the criteria and the current map segment, the second pushpin data representing a second location on the map. 9. A method comprising: displaying a map on a wireless communication device, the map formed by a plurality of rectangular map segments simultaneously displayed on the wireless communication device;sending, to a server, criteria for identifying at least one pushpin location;receiving, from the server, first pushpin data indicating a first pushpin location on the map and meeting the criteria;indicating the first pushpin location on the map;sending, to the server, updated location information indicating a current map segment of the plurality of map segments, the current map segment including a device location of the wireless communication device on the map;receiving, from the server, second pushpin data indicating a second pushpin location on the map and meeting the criteria; andindicating the second pushpin location on the map.
