JQM 1.3 input fields, border:none; does not work

JQM 1.3 input fields, border:none; does not work

In JQM 1.2:

.noborders{
      border: none !important;
      box-shadow: none important;
}
.
.
.  
<input type="text" id="text1" class="noborders"....>

hide text1 borders.

This does not work in JQM 1.3 !
