We have a sample in the SDK which from the sounds of it does what you are asking for.  Have a look at it here.

Thanks for your reply.I have achieved the compass.Firstly i set the point which stands for the phone-location on the map with a picture.The program received the angles from the Sensor and timely update the point use api "GraphicsLayer.updateGraphic(int id, Graphic graphic)".Just like this picture [ATTACH=CONFIG]27278[/ATTACH]

In our application, we have implemented a compass that rotates if the user rotates the map using the gesture. I have uploaded a sample project based on the esri compass sample. See below link
