I am wondering whether or not to activate my Graphene Mobile theme as so many of my site visitors are on mobile devices. However, I have some questions:

1 What mobile devices are automatically directed to the mobile site? For example, I would prefer iPad and tablet users to continue to direct to the non-mobile site - is this possible?

2 Is there a simple home page link mobile device users can click on to view the non-mobile site if they prefer?

3 Are there any consequences for the search engines? Are pages duplicated, or does having 2 versions of one url upset the organic search engine rankings on google etc?

4 Is Graphene Mobile compatable with my google Adsense? I notice my adsense ads don't display currently on mobile devices.

Thank you
