The 813SH for Biz is a business version of the 812SH, it is designed for companies that need to protect commercial secrets. Bluetooth and infrared data transfer is banned, but Bluetooth headsets are still supported. On top of that, email file attachment function is removed, external memory slot and Felica electronic money chip are also removed. The “813SH for Biz” supports a new service that allows you to destroy all data on the 813SH remotely when it’s stolen, needless to say the remote-lock is still in place. The super secret phone will be out in the market in March. Japan only. — Sam Chan
