The Pharos GPS Phone 600 is poster child of convergence. It’s a phone, a PDA, a camera, an FM radio, and the first Windows Mobile device to come with a full-featured navigation application in the U.S. The 600 comes with Pharos' OSTIA software, with its turn-by-turn navigation system and a host of navigation utilities. The reviewer liked testing the Pharos GPS Phone 600, because it’s truly an all-in-one device. There may be problems for first time users, however, since learning how to use OSTIA takes a bit of getting used to. If you get stuck, take heart because Pharos provides impressive customer service. A support team will take care of any issues you may encounter with the device or software.
