.htaccess rule to redirect to mobile URI help needed

Hello, I am needing to redirect website visitors to a mobile site based on the user agent information. I've found below code in research and works ok for iphone and android, but I need to redirect to equivalent pages between the desktop and mobile site. For example, if a mobile visitor lands on www.website.com/page5.html, they need to redirect to m.website.com/page5.html. The below code only redirects mobile visitors to  http://m.website.com.

I've experimented with adding:

RewriteCond %{REQUEST_URI} ^/$
RewriteRule ^ http://m.website.com%{REQUEST_URI} [R,L]

Select allOpen in new window

in a few different ways to the below code, but doesn't seem to work. Does anyone know of how I can alter the below working code to redirect to specific pages / URIs?

Thank You!

Current Code:

RewriteEngine on
RewriteBase /

RewriteCond %{HTTP:x-wap-profile} !^$ [OR]
RewriteCond %{HTTP:Profile}       !^$ [OR]
