The magnetic attachment means includes a magnet fixed to the main body, and a piece of iron attachable to the back of the mobile telephone and attachable to the magnet by magnetic force. The angle controllable supporting means comprises a pair of independently moveable hinge-connected supports which are also hinge-connected to the bottom of the main body.
