var mobileAgent = new Array("iphone", "android", "blackberry", "webos", "incognito", "webmate", "bada", "nokia", "lg", "ucweb", "skyfire");
      var browser = navigator.userAgent.toLowerCase();
      var isMobile = false;
      for (var i=0; i<mobileAgent.length; i++){
          if (browser.indexOf(mobileAgent[i]) != -1){
              isMobile = true;
              location.href = 'http://m.wanmi.com/';
