Need help - Subdomain templates doesn't work for Iphone

I have installed JM according the video tutorial and made the same changes in my CMS Admin environment. Changes made:

• Domain (multisite) support : Yes
• Domain name : iphone.van-haaften.nl
• Redirect to domain : Yes
• Component on home page : Yes

Unfortunately I have no real content on my Iphone, meaning no more then the standard index.html message, see iphone.van-haaften.nl How do I connect the Iphone template to my original website content? Shouldn't I have an index.php in the ../subdomains/iphone/httpdocs folder instead of the standard index.html? I have been doing all sorts of trial and error test (mainly error ). I'm using Plesk See image - tree structure

In your case sudomain is an independent site. MJ requires subdomain to be alias of the main domain, that is (even without MJ) visiting subdomain user gets the same content as on main site.
