hi
Under Applications / Installations, I've activated "Allow installations from non.Store sources.

When I attempt to install "Developer mode" under Security I get the warning "Enable developer mode?" and after I select ok I get the "Uncertified source" warning and i agree. nothing happens and the Developer mode switch goes off again.

What else do I need to install developer mode on a Swiss Cyan MeeGo 1.2 Harmattan N9-00 ?
