im trying to figure out the compass feature.
im not sure builtin gps would be that accurate to know which direction you face the phone by just holding it in center vertical position..

im thinking its the accelerometer thats making it motion left and right.. if thats the case then its not much of a compass. Unless their idea is to use google street view in conjuntion with gps navigation and "compass mode" to see on the phone what you see.
