DiscoverOurTown, an Internet city guide for 2,000 USA cities, is now available in a mobile GPS-enabled format for Palm OS and Windows Mobile PDAs and smartphones. The new travel guides are powered by Earthcomber, a mobile service that matches people’s favorite interests to spots around them. Anyone interested in exploring towns of all sizes along America’s highways will enjoy these free listings–travelers select favorite types of amusements, eateries, historical points and other interests, and Earthcomber alerts them to nearby attractions that match. As people travel through an area, DiscoverOurTown can help them find local hotels, unique shops, local services, restaurants, businesses, events and relocation information. All users of Earthcomber automatically receive the DiscoverOurTown listings when they download Earthcomber maps and location data.
