adding www to URL with Wordpress, IIS and Mobile enabled sites (m.)

Hi Experts,

I have an issue with URL rewrite Module.
I am getting infinite loop issues.

Problem:
When I type in "truesecrets.com.au" I am getting infinite loop when I want it to 301 redirect to "http://www.truesecrets.com.au/strange-tours-melbourne/"
Also when I type in "m.truesecrets.com.au" I get the same error, it should redirect to "http://m.truesecrets.com.au/strange-tours-melbourne/"

Setup
IIS 7
Wordpress v3.2.1

WordPress address (URL): http://www.truesecrets.com.au/strange-tours-melbourne/
Site address (URL): http://www.truesecrets.com.au/strange-tours-melbourne/

Plugins Installed:
PrettyLink

Current IIS web.config rewrite rule

<rewrite>
			<rules>
				<rule name="Redirect /(.*) to /strange-tours-melbourne/(.*) " enabled="true" stopProcessing="true">                 
					<match url="(.*)" />                    
					 <conditions logicalGrouping="MatchAny">   
						<add input="{REQUEST_URI}" pattern="^/strange-tours-melbourne/(.*)$" negate="true" />                      
					 </conditions>  
					<action type="Redirect" url="http://{HTTP_HOST}/strange-tours-melbourne/{R:1}" appendQueryString="false" redirectType="Permanent" />                
				</rule> 
			</rules>
		</rewrite>
