logo and search box poblems

[Evren]

hello,
I resized my logo to 250X67 pixels and edited the css as it is below, logo is uploaded to the @2x folder as well. Logo looks ok in pc browsers, however it is not shown fully in safari and chrome browser when I open with iphone.
Another probem I have is the search box looks over the featured ads when I visit the site with iphone. Please help me.

site is www.teknerehberi.com





The edit I made to the css.

div#logo {
width: 250px;
height: 67px;
float: left;
padding-top: 12px;
