Trimble Outdoors brings basic GPS services to select Alltel phones, though it appears to be meant more for hikers and mountain bikers rather than drivers. First, you must plan your trip online, but you then can send the routing information including maps and waypoints wirelessly to your phone.
The maps, which come in topographic, street, and aerial view, will show a "bread crumb trail" for reference. You'll be able to mark and edit waypoints during your journey, and use an integrated digital compass to display coordinates, speed, and heading. You'll also be able to geotag photos, audio, and video along your route and browse trips created by other users. It all sounds cool, provided you get good reception in the woods.
Trimble Outdoors will cost you, of course. You'll pay a daily fee of $1.99 for each day you use it, but Alltel also offers rates of $5.99 per month and $39.99 per year. Supported phones include the Motorola Razr V3A, V3C,
