    Compass is not in the list of the hardware interactions supported by the simulator and CLLocationManager headingAvailable reports it’s not available on the simulator.

    Also, in this doc:

    http://developer.apple.com/library/ios/#documentation/CoreLocation/Reference/CLLocationManager_Class/CLLocationManager/CLLocationManager.html

    Some location services require the presence of specific hardware on
    the given device. For example, heading information is available only
    for devices that contain a hardware compass. This class defines
    several methods that you can use to determine which services are
    currently available.

    Specifically CLLocationManager has this class property to check if the compass is available:

    + (BOOL)headingAvailable

    If I run this under the simulator:

    NSLog(@"headingAvailable: %d", (int)[CLLocationManager headingAvailable]);

    Outputs:

    2011-11-08 22:38:26.873 Craplet[39975:b603] headingAvailable: 0
