Just answered my own question.
I created a Plugin:
Product: vBulletin
Hook Location: Global Complete
Title: Disable vBAdvanced for Mobile Style
Execution Order: 2
Code:
PHP Code:
if ($vbulletin->userinfo['styleid'] == 5)
define('SKIP_OUTPUT', 1);
IMPORTANT - Make sure to replace "5" with the ID to your mobile style. This will basically set a flag for vbAdvanced to NOT process the template output.
If anyone has feedback, post it up. Hope this helps someone.
