Nokia looks to add location-based features to cell phones: While this is a Wi-Fi blog, I'd be remiss in not noting the coming closer-integration of global positioning satellite (GPS) receivers in a greater variety of equipment, including phones and cameras. (Ricoh and Pentax sell cameras with GPS integration, while Sony offers a GPS-timestamping device that can be synchronized via software later with the pictures you took.) And recall that Skyhook Wireless offers a Wi-Fi-based GPS-like service that could be integrated into mobile phones to work in concrete canyons in which GPS satellites are hard to spot, but cell towers and Wi-Fi transmitters are abundant.
AOL's Mapquest division, internetnews.com reports, released a GPS-based navigation system for mobile phones last April. Flickr, the Yahoo-owned online photo sharing and archiving service, just added geotagging this week, which allows photographs to be labeled with latitude, longitude, and level of map detail, and then clustered on maps.
