While I didn't change the location of the avatar, username and user info (e.g., Join Date, Posts, Title...) the modification works. Here's the instructions:

In postbit template:
1. Look for this (or something similar to):

			<if condition="$show['avatar']"><td class="alt2"><a href="member.php?$session[sessionurl]u=$post[userid]"><img src="$post[avatarurl]" $post[avwidth] $post[avheight] alt="<phrase 1="$post[username]">$vbphrase[xs_avatar]</phrase>" border="0" /></a></td></if>
			<td nowrap="nowrap">

and replace it with:

<!-- _______ CUSTOM AVATAR (FLASH) _______ -->
			<if condition="$post['field20']">
<!-- Flash Avatar -->
<if condition="$post['field20"><td class="alt2"><a href="member.php?$session[sessionurl]u=$post[userid]">
<object width="128px" height="128px">
<param name="movie" value="$post[field20]">
<embed src="$post[field20]" width="128px" height="128px" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash">
</embed>
</object></a>
</td></if>
<!-- End -->
                        <else />
<!-- vB Avatar -->
			<if condition="$show['avatar']"><td class="alt2"><a href="member.php?$session[sessionurl]u=$post[userid]"><img src="$post[avatarurl]" $post[avwidth] $post[avheight] alt="<phrase 1="$post[username]">$vbphrase[xs_avatar]</phrase>" border="0" /></a></td></if>
<!-- End -->
                        </if>
<!-- _______ END _______ -->
			<td nowrap="nowrap" valign="top">

2. Click "Save" and you're done.

*All of the other instructions remain the same. It's just with "postbit" template and not "legacy".

**While I'm not crazed with the other look (e.g., Username and user's info at the right of the avatar) that can be modified easily by replacing the <td> tags. If you need help with it let me know.
