Update (moderncv v2.0)
With moderncv v2.0, we have to completely redefine \makecvhead to achieve what you want, so add the following lines in your preamble:
\makeatletter

Original answer (works with older versions of moderncv)
With a little bit of hacking inside your code..., I've changed these lines
% \begin{minipage}[b]{\makecvtitlenamewidth}%
\raggedright\namestyle{\@firstname\ \@familyname}\par\medskip%
\ifthenelse{\equal{\@title}{}}{}{{\centering\titlestyle{\@title}\par}\medskip}%
%\hfill%
% detailed information
% \llap{
%
\usebox{\makecvtitledetailsbox}%
%\end{minipage}\ignorespaces%
%}% \llap is used to suppress the width of the box, allowing overlap if the value of makecvtitlenamewidth is forced
% optional photo (rendering)
\usebox{\makecvtitlepicturebox}\\[2.5em]%
to
\begin{minipage}[b]{\makecvtitlenamewidth}
\raggedright\namestyle{\@firstname\ \@familyname}\par\medskip%

\usebox{\makecvtitledetailsbox}%

and the result is
