The Optimus V is my first delve into the world of smartphones. I'm figuring somethings out...slowly but I have a few questions. I understand that this phone has GPS. 1) How would a person use it for geocaching? Is that something built into the phone? 2) Also, is there a way to track a route that I've traveled using this phone? I plan to drive part-way cross country this summer and I would like to record the route I've driven and display it on a map after the trip is completed. 3)Can the GPS features of the phone work without a connection to the internet? Thanks.
