Go to Maps, get into street view, click menu, and click on Compass mode. Never knew this was there. ...........Doh!
Pretty cool I suppose. Would be nice if it calibrated a little differently. Normally you look at your phone at an angle. With compass mode on you'd be looking at the ground unless you hold it straight up in the air like some tourist or off planet visitor running diagnostic scans.
You have to be in a popular area, not all streets have street view, like small towns and rural area's.
