So when i picked up the 3g iPhone, the first thing i played with was the location services.. my device was located, the blue sphere was present and moving along as i drove my car. However, when it got to the edge of the screen, it kept goin, and the map stayed stationary! I thought it was sorta lame that i would have to drap the map to keep up with the blue dot..However, today as i routed a direction, and called upon the blue circle, as it traveled,the map actually moved to keep up with it! so it will do this if a course is plotted! thought it was neat.. thanks for reading!
