Enable opc only for default Joomla tpl. not for mobile tpl.

[virtualsoft@.....com]

Joomla 2.5.6
Virtuemart 2.0.10

Hello,

I have a Virtuemart webshop with a default desktop template and a mobile template (Jtouch 2.5.20 from http://www.jtouchmobile.com). I want to use OPC 2 for my default desktop template only.
For the mobile template I would like to keep the standard virtuemart checkout page. How can I accomplish that?

Thanks for your help!
