MapQuest, Research in Motion-manufacturer of the Blackberry personal digital assistant-and Sprint Nextel jointly announced the availability of MapQuest’s “Find Me” location-based application on Blackberry 7520 handsets operating on Nextel’s national network.

The Find Me application lets users find their location, access maps and directions, and locate nearby points of interest. A group communication function lets users create private networks in which members can share their current locations, as well as locate other members and identify their locations via a “buddy-list” feature.

In addition, users can create alerts that will notify them through SMS or e-mail when other opt-in users arrive at or depart a given location.
