I too went through several design changes before finding some that I was satisfied with (for now). I'm still not completely happy but they are enough to get me started. I still have to make buttons for the actual devices and work on the layouts. All my time so far was spent making home page icons. I did go overboard and made them for every device I could think of (I program a lot of these things for work). I must again thank Archer. If it wasn't for his how-to and email help I wouldn't have known where to start to make all the buttons that I have.
