Icon background and iPhone 4

[Folke Sonin]

Just got my iPhone 4 today and noticed that the main icon for the app does not actually have a transparent background like I had always assumed. The black square is ugly superimposed on the wave I choose as my background. Please make the non shield part transparent.

Also, any ETA on a graphics update for the Retina Display? After I play tonight I can update this post with specifics if needed.

Thank you for such an awesome game.
