After sifting around the InterTubes all morning, I found a few articles about redirecting mobile viewers through the .htaccess file.
...Mobile Joomla appeared to be working IF you typed in the sub domain into your mobile device. But it wouldn't redirect visitors to the mobile URL if they typed in the 'regular' URL.
After much trial and error, here's what's in my .htaccess file (for anyone else with a similar problem, hopefully this'll help)...
# don't apply the rules if you're already in the mobile directory, infintine loop
# you'll want to test against the host if you're using a subdomain
#RewriteCond %{REQUEST_URI} !^/mobile.twiskonline.com/.*$
# if the browser accepts these mime-types, it's definitely mobile, or pretending to be
RewriteCond %{HTTP_ACCEPT} "text\/vnd\.wap\.wml|application\/vnd\.wap\.xhtml\+xml" [NC,OR]
# a bunch of user agent tests
RewriteCond %{HTTP_USER_AGENT} "sony|symbian|nokia|samsung|mobile|windows ce|epoc|opera" [NC,OR]
RewriteCond %{HTTP_USER_AGENT} "mini|nitro|j2me|midp-|cldc-|netfront|mot|up\.browser|up\.link|audiovox"[NC,OR]

RewriteCond %{HTTP_USER_AGENT} "portalmmm|blazer|avantgo|danger|palm|series60|palmsource|pocketpc"[NC,OR]
RewriteCond %{HTTP_USER_AGENT} "smartphone|rover|ipaq|au-mic,|alcatel|ericy|vodafone\/|wap1\.|wap2\.|iPhone|android"[NC]
RewriteCond %{REQUEST_URI} ^/$
#RewriteRule ^$ /mobile.twiskonline.com/ [L,R=302]
RewriteCond %{HTTP_HOST} "!mobile.twiskonline.com" [NC]
RewriteRule (.*)
mobile.twiskonline.com/$1 [L]
