Wikinear is a service, not a content site. It uses FireEagle to pass along your location (via whatever tech is used), along with other Goodies (Wikipedia, Oath, GeoNames, Google Maps) to return 5 POIs from Wikipedia to you. Since FireEagle is still in beta many won't be able to use it yet.

winners in Mobile Rules (Nokia's dev contest):
Best Application - Infotainment:
Earthcomber. These guys are working on ways to exploit GPS technology in mobile phones. Their winning entry involved a partnership with the Travel Channel where a visitor to Chicago could choose to be informed of attractions and sites around his or her current location.
