I have to say that the best application for Windows Mobile, just got better. The newly released version of Google Maps for Windows Mobile not only hosts a new user interface, it also supports Google Latitude. Essentially Google Latitude, with your permission of course, allows you to track and share your location. It’s as easy as signing in with your Google account.
Once you’re in you can add and remove friends. You can of course control how visible your location is via the Privacy tab.
At this stage there is no API available according to postings on the Google Mobile forum.
Get started with the latest version of Google Maps with Latitude by going to http://google.com/latitude on you device.
