Good news this mod if you install and read the simple instruction the description page at SMF will detect when an iphone or any mobile unit is viewing you page and show what ever theme you select to be shown, it also removes the side panels so you main content and page is shown in their little devices making easier for them navigate your site. I have it on my site and tested it with my small Android phone and it works as expected to!
