Making Mobile View Default

[kabal]

Hi,
I have some users in remote offices and the link there can be horrendous.
Anyway, in the default class of service, I set HTML to be the default view but this view seems to have issues showing the messages full text.

I want to make mobile view the default view but the option is not avalable on the admin console.

When I tried to do it via command-line, I got stuck. These are the entries I saw:

[zimbra@mailserver ~]$ zmprov gc default | grep -i html
zimbraAttachmentsViewInHtmlOnly: FALSE
zimbraFeatureHtmlComposeEnabled: TRUE
zimbraFeatureViewInHtmlEnabled: FALSE
zimbraNotebookSanitizeHtml: TRUE
zimbraPrefHtmlEditorDefaultFontColor: #000000
zimbraPrefHtmlEditorDefaultFontFamily: Arial, Helvetica, sans-serif
zimbraPrefHtmlEditorDefaultFontSize: 12pt
zimbraPrefMessageViewHtmlPreferred: TRUE

My assumption is that I am to change the following:
zimbraFeatureViewInHtmlEnabled: FALSE

But where do I specify mobile view?

What do I change to make mobile the default view?
Any ideas?
