I have a class called MainGame, which is defined like this in my .h:

@interface MainGame : Renderer <UIAccelerometerDelegate>

Then later in my .m I have this:

- (void) accelerometer: (UIAccelerometer *)accelerometer didAccelerate: (UIAcceleration *)acceleration {
    // here I would read values like accelerometer.x
    NSLog(@"accelerated!!1");
}

Am I doing it right?

Currently I'm only testing in iPhone simulator, I'm going to buy the apple $99 developer thing soon. It doesn't log "accelerated!!1", but I'm guessing that's because I'm not running it on an actual device yet?
