Several Nokia Series 60 phones now have integrated GPS - useful for locating your position when touring. The default software in Nokia phones supports latitude and longitude coordinates in decimals degrees. But IGN maps in France are marked in “UTM” grid coordinates, and OS maps in UK are marked in “OSGB” coordinates. So I wrote a free “beta” software that converts the GPS coordinates from decimal degrees into UTM and OSGB coordinate formats. With these coordinates, you can locate your position on a paper map.
It can also do some other useful stuff, like converting manually entered UTM and OSGB coordinates and saving these as Landmarks in decimal format in the Nokia device for use with other navigation applications in the phone. If you have a Nokia phone S60 supporting GPS such as N95, E90, 6110 Navigator - do try it.
