Show which way you’re facing (iPhone 3GS only):  Tap   again. (The icon changes to 
.) Maps uses the built-in compass to determine which way you’re facing. The angle 
shows the accuracy of the compass reading—the smaller the angle, the greater the 
accuracy.
Maps uses true north to determine your heading, even if you have magnetic north 
set in Compass. If the compass needs calibrating, iPhone asks you to wave the phone 
in a figure eight. If there’s interference, you may be asked to move from the source of 
interference. See Chapter 22, “Compass,” on page 173.

A pin drops down on the map, which you can then drag to any location you choose.
Replace the pin:  Tap  , then tap Replace Pin. iPhone drops the pin in the area you’re 
currently viewing.
