While this is probably considered blasphemous, I don't like the cow icon, especially on my iphone. There are javascript tricks to change the default icon (iclypso.com details one such trick) that I can use to change my other icons but it DOES NOT work with RTM even though it works with other sites that provide a web clip icon (amazon, digg).

Any idea why? Can anyone else override it? I was able to do so before RTM supplied the cow one.

Love the service, just not the cow :P
