Hi,
In this case I will answer your original question. But maybe tell your client that support of many new devices (which did not exist when 5.5 version was released) was added in 7.0 versions. It means they are not supported. I mean a redirection on this devices is not working in 5.5.
As for your question. If you take a look at the screenshot from the documentation you will see the Home document on the main site and Home document in the mobile section.
In the mobile version of Home page is inserted a repeater web part with a transformation configured to:
<%# GetEditableValue("wC") %>
*wC is a code name of editable text control inserted on the main Home page.
I hope it makes sense.
If you decided to develop a mobile version of site I suggest you to watch webinar about responsive design. It may be useful for you:
