This theme is used for presenting Your information to Smartphone visitors, which is increasing in numbers day by day.
BG Webshop comes with a default theme layout, that looks very much like the iPhone styling of things.
If you need to change the colors, layout or other items on the default, you should download this theme, which is a copy of the default tpl-files.

This theme is actually a sub-theme, so it'll be placed within a theme of your choise in it's own folder.
If you want to add some custom/local changes to any of the following tpls, first you have to place that tpl in your site’s themes/<current theme>/mobil folder.
You can Edit with the Theme-editor in Your administration.
