There is a difference in 'true north and magnetic north'. True north points to what is commonly thought of as north, the north pole - aka the top of the world where the axis is, follow the North Star.' Magnetic north is where compasses point, some spot in Siberia right now, depending on where you are in the world true north and magnetic north can be up to 18 degrees apart. The military has their own called grid north, the world is broken down into 1 kilometer grids, I don't know the origin point but because of the shape of the world, grid north is also off from true and Magnetic by up to a large amount of degrees to.

If you are using your 3G S to navigate with as a compass you should calibrate it away from anything metal, including small items on your person and use it with magnetic north. Otherwise you'll get lost quickly.
