Footer adds padding to right. Why?

Footer adds padding to right. Why?

Hey all. I've been wrestling with footer issues and can't banish the issue. Which is:

When I add a footer to my web app it adds padding to the right. I can only confirm this on iPhone as I've not yet gone to "the lab" (my local AT&T store) to test this on other platforms :)

The padding is initially off screen. But, I can do a right swipe and MAKE the padding appear.

If I remove the footer, the padding disappears.

I've run the html through several tidy passes... the divs checkout a-ok. I wonder about the CSS. But, confess, I'm not up to speed in that department.

Any/all help appreciated.
