Slight redesign. Work with me here on the visual...
Instead of the power button and it's "icon" facing you when you look at the face of the phone, now you just see the black plasitc side of the raised button. Now, when looking down on the top of the phone you see the power button icon.
So instead of fidgeting to hit the button "just right", now you simply press down on a raised button. Very simple and minor change, but it makes the use of that button very easy! I don't have a camera right now, hopefully I can get my mits on one soon to snap a quick photo for you in case I can't find one on the net.
