If Siemens is trying to unload its ailing mobile handset business, it will have to try doing this just a bit harder.  According to a report in yesterday's Frankfurter Allgemeine Zeitung German daily, just as Motorola execs were about to sign an agreement between both companies, they had a last minute change of heart and backed away from the deal.  This is a bit of a setback for Siemens, but I'd be willing to bet that there could be a potential suitor down the road (maybe an Asian player such as Samsung or LGE).
