Well, Cingular's just having a field day today. In addition to announcing the availability of the long-awaited HP iPaq hw6920, the cell phone carrier launched its first location-based service, called TeleNav GPS Navigator, for its business and government customers. The service costs $9.99 per month for unlimited use (or $5.99 per month for up to 10 trips) and provides text- and voice-guided turn-by-turn directions and color maps so that you don't miss that important client meeting. In addition to the standard nav features, there are some extra handy tools, including a Biz Finder for searching local businesses, a Fuel Finder, and a Spot Marker so that you can find your car wherever you parked it. TeleNav GPS Navigator is available on the GPS-enabled HP iPaq hw6920, the HP iPaq hw6515, the Cingular 8125, and the Palm Treo 650. If you own the 8125 or the Treo, you will need a Bluetooth GPS receiver, however. And hey, Cingular is currently offering a free one-month trial, so why not take it out for a test-drive?
