Pushing Apple's Buttons: iPhone 4 split volume buttons not as good as single volume button

The first design flaw I noticed on the iPhone 4 is the separate volume buttons. Because the up/down volume buttons are split (and so far apart), it's difficult to tell if I'm on the volume up button or the volume down button.

I have to feel around for the second button to 'see' if I'm on the top button or the bottom button.

Apple, please go back to a single saddle-button solution (as on the original iPhone or feel free to use my design--after we talk about royalties):
Top section: volume up.
Bottom section: volume down.
