Launch image VS SplashScreenImage on iPhone5

Okay, I ended up creating a DynamicSplashScreen Class in ActionScript and it looks like it's working. I changed the splashScreenImage property in my default mxml file to point to the new Actionscript class. While debugging it, I noticed it seems to call getImageClass 2x and the first time through the resolution is always 1000 - even on the iPhone 4. Not sure why this is happening, but I wanted to point it out. The only thing that I noticed is that when viewing on an iPhone 5/iPod Touch 5, I noticed that there is a slight shift with the image after a second. I am assuming that it is moving from the launch image in the src directory to where I have the splash image in the assets folder. Haven't found a way to fix this yet. There might be a better way to do this, but for now this should hopefully work!

package views
{
    import flash.display.StageAspectRatio;
    import spark.preloaders.SplashScreenImage;
    import spark.preloaders.SplashScreenImageSource;
    public class DynamicSplashScreenImage extends SplashScreenImage
    {
        protected var s1:SplashScreenImageSource = new SplashScreenImageSource()
        protected var s2:SplashScreenImageSource = new SplashScreenImageSource();
        protected var s3:SplashScreenImageSource = new SplashScreenImageSource();
        [Embed(source='assets/Default.png')]
        protected var s1Source:Class;
        [Embed(source="assets/Default@2x.png")]
        protected var s2Source:Class;
        [Embed(source='assets/Default-568h@2x.png')]
        protected var s3Source:Class;
        public function DynamicSplashScreenImage()
        {
            super();
        }
        override public function getImageClass(aspectRatio:String, dpi:Number, resolution:Number):Class
        {
            var splashClass:Class;
            s1.source = s1Source;
            s2.source = s2Source;
            s2.minResolution = 920;
            s2.aspectRatio = flash.display.StageAspectRatio.PORTRAIT
            s3.source = s3Source;
            s3.minResolution = 1096;
            s3.aspectRatio = flash.display.StageAspectRatio.PORTRAIT
            switch(resolution){
               // iphone 5
                case 1096:
                    splashClass = s3Source;
                    break;
               // iPhone 4
                case 920:
                    splashClass = s2Source;        
                    break;
               //iPhone 3
                default:
                    splashClass = s1Source;
                    break;
            }
            return splashClass;
        }
    }
}

Hope this helps!
