How to unpublish component but still use templates?

I want to use my default responsive template for my "iphone version website"... but still want to use the mobile_iphone template on specific pages, when specified via the url.

How can I unpublish the component "Mobile Joomla" for it not to intercept iphone traffic, but still use the component's templates directly on menu assignments or specified as index.php?template=mobile_iphone

Please any ideas...

Just set empty value for "Template" field and disable image rescaling in all MJ settings tabs except of iPhone one.

If you remove MobileJoomla component, the mobile_iphone template will not work.
