Nokia took drastic action to improve its ailing smartphone business through a swap of executives as well as a reorganization of the company itself. Its Devices group has been split into a group for Smartphones, covering more advanced devices, as well as Mobile Phones, for its conventional Symbian S30 and S40 cellphones. The firm has also taken the unusual step of moving its chief financial officer, Rick Simonson, to head up the Mobile Phones group.
