Silverson,
I used this question for the subject of a quick tutorial: http://youtu.be/qi_idD1lixI 3:52

In skin /common_files/modules/One_Page_Checkout/summary/cart_totals.tpl around line 50 you will see this code:

{if $config.Shipping.enable_shipping eq "Y"}
    <tr>
      <td class="total-name dcoupons-clear">
        {$lng.lbl_shipping_cost}{if $cart.coupon_discount ne 0 and $cart.coupon_type eq "free_ship"} ({$lng.lbl_discounted} <a href="cart.php?mode=unset_coupons" title="{$lng.lbl_unset_coupon|escape}" class="unset-coupon-link"><img src="{$ImagesDir}/spacer.gif" alt="{$lng.lbl_unset_coupon|escape}" /></a>){/if}:
      </td>

      {if ($shipping ne '' or not $need_shipping) and $userinfo ne "" or $config.General.apply_default_country eq "Y" or $cart.shipping_cost gt 0}
        <td class="total-value">{currency value=$shipping_cost}</td>
      {else}
        <td class="total-value">{$lng.txt_not_available_value}</td>
      {/if}
    </tr>
{/if}

Simply wrap this in an additional if statement:

{if $cart.shipping_cost gt 0}
 Original code goes here
{/if}
