Trimble may make plenty of GPS-equipped devices of its own aimed at adventure-minded folks, but its Trimble Outdoors software has also made quite a few cellphones a bit more outdoors-friendly, and it's now finally found its way to the T-Mobile G1. As with on some other phones, the app will let you plan your trip online and sync it up with your G1, and give you the ability to geotag pictures, log your trip and share it with others, take text and audio notes and, of course, simply use it as a full-fledged GPS navigator. That won't come free, of course, but the $19.99 app price sure is a good deal cheaper than a separate outdoors GPS device, and you can grab it right now from Android Market.
