Here's what I have working successfully on 4.1.3:

1. Create a new file skin1/customer/main/sexy_customer_details.tpl with this code:

{* $Id: sexy_customer_details.tpl,v 1 2006/06/01 15:15:52 max Exp $ *}
<table width="100%" border="0" cellspacing="0" cellpadding="0">
<tr>
<td><div class="sidebox">
<div class="boxhead"><h2>{$lng.lbl_personal_information}</h2></div>
<div class="boxbody">
{if $userinfo.default_fields.firstname}{$userinfo.firstname} 
{if $userinfo.default_fields.lastname}{$userinfo.lastname}{/if}{/if}
<br/>
{if $userinfo.default_fields.phone}{$lng.lbl_phone}: {$userinfo.phone}
{/if}
<br/>
{if $userinfo.default_fields.fax} {$lng.lbl_fax}: {$userinfo.fax}
{/if}
<br/>
{if $userinfo.default_fields.email} {$lng.lbl_email}: {$userinfo.email}{/if}
</td>
<td></td>
</tr>
<tr>
<td><div class="sidebox">
<div class="boxhead"><h2>{$lng.lbl_billing_address}</h2></div>
<div class="boxbody">
{if $userinfo.default_fields.firstname}{$userinfo.b_firstname}{if
$userinfo.default_fields.lastname} {$userinfo.b_lastname}{/if}{/if}
<br/>{if $userinfo.default_fields.b_address}{$userinfo.b_address}{/if}
{if $userinfo.b_address_2}<br/>{$userinfo.b_address_2}{/if}
<br/>
{if $userinfo.default_fields.b_city}{$userinfo.b_city}, {/if} 
{if $userinfo.default_fields.b_state}{$userinfo.b_statename} {/if} 
{if $userinfo.default_fields.b_zipcode}{$userinfo.b_zipcode} {/if}
<br/>
{if $userinfo.default_fields.b_country}{$userinfo.b_countryname} {/if}
 </div>
</div></td>
<td><div class="sidebox">
<div class="boxhead"><h2>{$lng.lbl_shipping_address}</h2></div>
<div class="boxbody">
{if $userinfo.default_fields.firstname}{$userinfo.s_firstname}{/if}{if
$userinfo.default_fields.lastname} {$userinfo.s_lastname}{/if}
<br/>
{if $userinfo.default_fields.s_address}{$userinfo.s_address} {/if}
{if $userinfo.s_address_2}<br/>{$userinfo.s_address_2} {/if}
<br/>
{if $userinfo.default_fields.s_city}{$userinfo.s_city}, {/if} {if $userinfo.default_fields.s_state}{$userinfo.s_statename} {/if} {if $userinfo.default_fields.s_zipcode}{$userinfo.s_zipcode} {/if}
<br/>
{if $userinfo.default_fields.s_country}{$userinfo.s_countryname} {/if}
</div>
</div></td>
</tr>
</table>

2. Open skin1.css and add this at the bottom:

.sidebox {
margin: 0 auto;
width: 28em;
background: url(images/sbbody-r.gif) no-repeat bottom right;
font-size: 100%;
}
.boxhead {
background: url(images/sbhead-r.gif) no-repeat top right;
margin: 0;
padding: 0;
text-align: left;
}
.boxhead h2 {
background: url(images/sbhead-l.gif) no-repeat top left;
margin: 0;
padding: 22px 30px 5px;
color: white;
font-weight: bold;
font-size: 1.2em;
line-height: 1em;
text-shadow: rgba(0,0,0,.4) 0px 2px 5px;
}
.boxbody {
background: url(images/sbbody-l.gif) no-repeat bottom left;
margin: 0;
padding: 5px 30px 31px;
}

3. Download the 4 images from the first post and save them in skin1/images.



4. Open skin1/customer/main/checkout.tpl and replace:

{include file="customer/main/customer_details.tpl"}

With:

{include file="customer/main/sexy_customer_details.tpl"}

Hope it works as well for you as it did for me!
