twentytwelve mobile issues

I’ve specified the background of my site’s front page as a gray color. For some reason the mobile version shows up with a white title box and a white main text area box. A search field shows up at the top as well for some weird reason. Additionally I’ve put a phone number in the text which on the mobile site defaults to a color I need to change.
