Jquery Mobile with .htaccess issues

I am currently using a separate site all together for my mobile site, using jquery mobile. I am using .htaccess to decide what version of the site to show the user.

What is happening is that the version shown on phones is very inconsistent. I can go to the site on any given time and sometimes the mobile site is shown sometimes its the desktop site.

RewriteCond %{REQUEST_URI} !^/mobile/.*$
RewriteCond %{HTTP_USER_AGENT} "android|blackberry|ipad|iphone|ipod|iemobile|opera mobile|palmos|webos|googlebot-mobile" [NC]
RewriteRule ^(.*)$ /mobile/ [L,R=302]

Any help would be appreciated.
