A mobile device having a messenger function and a method for supporting such a messenger function is provided. When a messenger function is activated, the mobile device receives messenger data from a presence server. This messenger data includes state information about other mobile devices connected to the presence server. Then the mobile device classifies the received message data according to at least one criterion among a device, a time, and a modified time, and then stores it as history data. Also, at a user's request, the mobile device outputs the history data of a selected other mobile device.

A pair of functional metal ion bands are provided. The pair of functional metal ion bands are attached to meridians and acupoints of the human body in a simple manner to induce a smooth flow of current in the body, thereby rapidly changing a disease condition to a normal state. The pair of functional metal ion bands comprise a gold-colored thin metal plate as a positive electrode and a silver-colored thin metal plate as a negative electrode wherein the gold-colored thin metal plate is composed of Cu and a metal selected from Ag, Au and Pt and the silver-colored thin metal plate is made of an alloy of Al, Si, Fe, Cu, Mn, Mg and Zn. The pair of functional metal ion bands are manufactured by processing each of the thin metal plates to have a thickness of 1 &#x3bc;m to 1 cm and a diameter of 1 mm to 50 cm, and attaching the processed metal plate to one side of a soft adhesive fabric using an adhesive.
