Mod_Rewrite Permalink Problem

I’ve put this mod_rewrite code in my .htaccess so that it will redirect funnyall.com to http://www.funnyall.com, it works but the problem is when i type http://funnyall.com/2006/12/05/funny-all-1/ it will redirect to http://www.funnyall.com/index.php

Is there any way to fix this problem so that when i type in http://funnyall.com/2006/12/05/funny-all-1/ it will redirect to http://www.funnyall.com/2006/12/05/funny-all-1/

Below is my code:

Options +FollowSymLinks
RewriteEngine On
RewriteCond %{HTTP_HOST} ^funnyall\.com$ [NC]
RewriteRule ^(.*)$ http://www.funnyall.com/$1 [R=301,L]

P/S: I’m using WP version 2.0.2
