title: iPhone 5 is not displaying the responsive mode of the website correctly
body: <p>I have created <a href="http://concordbuilders.com/" rel="noreferrer">this website</a>, and so far I have not been able to find out why only on certain iPhone phones, the website is not displayed in its responsive mode. (it shows correctly on most iPhone phones).</p>
  
  <p>Here is what I have done so far: </p>
  
  <ol>
  <li>Checked the website on Android devices: it looks good </li>
  <li>Check the responsive website on different browsers: it works</li>
  <li>Use online iphone simulators to see how the website looks: Shows fine</li>
  <li>Cleared browser cache and cookies on iPhone devices that have problem showing the responsive mode: Still no luck</li>
  </ol>
  
  <p>Here is a screen shot of how the website homepage SHOULD look like in iphones. </p>
