Do I have the ability on my HTC Desire to star my current location on google maps and give it a name? eg I wander past a nice bit of graffiti which I want to mark on my map. Can I start navigation, get found by gps and then name my location 'cool graf' and star it so that in future I can get directions back to it should I need them? If that's possible can someone let me know how? Any help much appreciated.
