Menus & Responsive Design

When we are in word press and we go to the menu section and make any changes to the main menu it does not change any of the menus on the website. We specifically want published pages that are not included in a submenu or drop down menu. Any help with these menu issues would be appreciated. Also, the responsive design works well with various computers and tablets, but not with the iPhone. Our site is www.birchwoodbaptist.org Any suggestions?
