I posted the same message in this forum, also including JomSocial, Mobile Joomla, and Kunena Forums which includes Groups.
There may be a solution if a plugin can be installed to work with "Mobile Joomla!". I wouldn't know who would do this, but I believe that if Mobile Joomla! works with JomSocial and Kunena, making both of these components mobile would be possible.
