Center Navbar in Twitter Bootstrap 2.0

Suppose we have the following markup for navigation bar using Twitter Bootstrap 2.0.

<div class="navbar navbar-fixed-top">
  <div class="navbar-inner pull-center">
      <ul class="nav">
      <li class="active"><a href="#">HOME</a></li>                        
      <li><a href="#contact">CONTACT</a></li>
      </ul>        
  </div>
</div>

What is the best way to center .nav inside navbar-inner?

I only came up with adding my own CSS styles:

@media (min-width: 980px) {
    .pull-center {
        text-align: center;
    }
    .pull-center > .nav {
        float:none;
        display:inline-block;
        *display: inline; *zoom: 1;
        height: 32px;
    }
}
