Setting width of entire layout.....

Setting width of entire layout.....

I created a custom theme using Theme Roller.  The issue is when I view the app in the iPhone simulator it the accordion widget and logo do not stretch the width of the device.  Also all of my text fields and buttons do not appear as the more modern style.

I'm using the WebMatrix iPhone simulator, not sure if that has anything to do with it.  I want the logo (red rectangle) more to the left and the accordion to span the width of the device.  Here is a picture of how the layout appears.
