logo/header image help

I want my mobile site to use the Site Logo in the header. (found in the ‘branding’ section of ‘theme settings’. I’ve uploaded my image, and even when I click ‘preview theme’ it all checks out.

But when I actually bring my site up on my iphone, it uses the banner that the desktop version of my site uses.

I really don’t want to use the banner for my mobile site, because I have different home pages for mobile and desktop, and clicking it sends you to the desktop home page.

What can I do to fix this?
