We went into Vodafone a couple of days ago after our old Sony phone finally gave up the ghost and came out with a Nokia N95. The N95 has been reviewed on many sites for its various multi-media/wi-fi/photographic abilities but what opened up our thoughts to move over to a Nokia was the built in GPS.
If you own a N95 one of the first things you should do is download the recently released free application 'Sports Tracker' from Nokia. Sports Tracker is aimed at the sports or general user on foot or cycling and more importantly it provides full route tracking with the ability to upload to Google Earth.
The ability to create tracks for Google Earth/Maps in a small portable portable phone is impressive. On our first test run we used the Sports Tracker application on a drive across Berkshire (its meant to be used for running or cycling but it does the same job in a car). The N95 performed well considering it was placed well inside the car, rather than on the windscreen as with most in-car GPS systems. After you have reached your destination you can simply choose to 'Save as Google Earth' and then transfer to your PC.
Once in Google Earth a variety of information points are provided on your travel speed as well as your highest and lowest altitudes. We have only touched on the basic level of functionality here but the N95 GPS comes highly recommended, it is definitely a step forward in Google Earth tracking for the general consumer.
