IPhone App Screen Design - Speed Gauge

THE CHALLENGE: Lets re-do this “simple” product and make it STUNNING! Everything is up to you.

I want to see screens that make people just want to stare at their iphones! Those of you who participated in the icon design challenge know how far we’ve come. We can’t stop here!
I’m surrendering my screens to you, take over, and throw away everything if you have to. Colors, graphics, layout (portrait/landscape) everything is up to you. I’d like to see some 3D concepts ( not a requirement ) As I’ve said, everything is up to you.
Here are the concept screens and explanations:

If you haven’t participated in the icon contest, search for “Speed Gauge” and take a look.

Product Description: The application calculates SPEED based on the distance and time the user enters. It will be targeted to RUNNERS. For example, if you ran 100 meters in 10 seconds, the application will display “22 MPH.”

- Screens in 320 by 480 pixel size. If your design is landscape then 480 by 320.- Screens in Adobe Photoshop format- Icons in Adobe Illustrator Format- If you use any “stock” images please let me know immediately, as soon as you submit a concept, and point me to the license agreement. I need to make sure we can use them ahead of time.

- Make sure icons are not too small, otherwise they won’t work.
