The white background in my apple touch icon turns black?? My white background isn't transparent. The icon has a white triangle, red circle and black text. The only thing I can make out is the white triangle and red circle. Any idea whats causing this and how to make the icon keep its white background? Much appreciated.

As gstricklind found, if your png has alpha channel transparency, iOS will unfortunately ignore any "precomposed" directive and apply all its usual effects, in adddition to giving your icon a black background (white didn't seem like a better choice??).
The solution is, of course, to precompile the icons with no transparency. This makes it pretty difficult to utilize Android's support of alpha channels while offering itouch icons as well if a black background does not work for you.
