I am not sure what f.e. means in the question.
The site is working for an iphone user agent in firefox. I attach two pictures.
It may be that you need to clear cache on the real iphone, and also clear all cookies.
It may also be true that you need to click on mobile view (at bottom of screen). The mobile view/standard view is not showing on the desktop view at the moment. You need to enable the mod_mj_markupchooser in the footer of the desktop template. The phone may have got "stuck" in standard view.
This post tells you how to use your pc/laptop to see the iphone images.
