15. A method for a communication device comprising a microphone, a speaker, an input device, a display, and an antenna, said method comprising: a function implementing step in which one or more specific functions are implemented; wherein said communication device implements a voice communicating function and a multiple language function; wherein a voice communication is implemented by utilizing said microphone and said speaker when said voice communicating function is implemented in said step; and wherein a 1st language data and a 2nd language data are pre-stored in said communication device, wherein said 1st language data indicates a 1st language and said 2nd language data indicates a 2nd language, wherein said communication device functions under a 1st language mode or a 2nd language mode when said multiple language function is implemented in said step, wherein said multiple language function is the functionality enabling the user to manipulate said communication device with the user's preferred language by displaying the user interface with the language selected by the user, wherein when said 1st language mode is selected by the user, a 1st language identification which indicates said 1st language mode is registered in a data storage area and a positive command which is the command for the user to manipulate said communication device in a first manner and a negative command which is the command for the user to manipulate said communication device in a second manner are displayed by utilizing said 1st language data, wherein when said 2nd language mode is selected by the user, a 2nd language identification which indicates said 2nd language mode is registered in said data storage area and said positive command which is the command for the user to manipulate said communication device in said first manner and said negative command which is the command for the user to manipulate said communication device in said second manner are displayed by utilizing said 2nd language data, wherein when said communication device is powered on after being powered off, the language identification stored in said data storage area is identified without the user's instruction implemented manually and said communication device automatically implements the language mode indicated by the language identification stored in said data storage area and said positive command and said negative command after said communication device is powered on are automatically displayed with said 1st language if said 1st language mode was selected by the user before said communication device was powered off, and said positive command and said negative command after said communication device is powered on are automatically displayed with said 2nd language if said 2nd language mode was selected by the user before said communication device was powered off, and wherein said positive command indicates an opposite instruction compared to said negative command.
15. A method for a communication device comprising a microphone, a speaker, an input device, a display, and an antenna, said method comprising: a function implementing step in which one or more specific functions are implemented; wherein said communication device implements a voice communicating function and a multiple language function; wherein a voice communication is implemented by utilizing said microphone and said speaker when said voice communicating function is implemented in said step; and wherein a 1st language data and a 2nd language data are pre-stored in said communication device, wherein said 1st language data indicates a 1st language and said 2nd language data indicates a 2nd language, wherein said communication device functions under a 1st language mode or a 2nd language mode when said multiple language function is implemented in said step, wherein said multiple language function is the functionality enabling the user to manipulate said communication device with the user's preferred language by displaying the user interface with the language selected by the user, wherein when said 1st language mode is selected by the user, a 1st language identification which indicates said 1st language mode is registered in a data storage area and a positive command which is the command for the user to manipulate said communication device in a first manner and a negative command which is the command for the user to manipulate said communication device in a second manner are displayed by utilizing said 1st language data, wherein when said 2nd language mode is selected by the user, a 2nd language identification which indicates said 2nd language mode is registered in said data storage area and said positive command which is the command for the user to manipulate said communication device in said first manner and said negative command which is the command for the user to manipulate said communication device in said second manner are displayed by utilizing said 2nd language data, wherein when said communication device is powered on after being powered off, the language identification stored in said data storage area is identified without the user's instruction implemented manually and said communication device automatically implements the language mode indicated by the language identification stored in said data storage area and said positive command and said negative command after said communication device is powered on are automatically displayed with said 1st language if said 1st language mode was selected by the user before said communication device was powered off, and said positive command and said negative command after said communication device is powered on are automatically displayed with said 2nd language if said 2nd language mode was selected by the user before said communication device was powered off, and wherein said positive command indicates an opposite instruction compared to said negative command. 16. The method of claim 15 , wherein one of said commands indicates either to open or close file, wherein said one of said commands displayed after said communication device is powered on is displayed (1) with said 1st language if said 1st language mode was manually selected by the user before said communication device was powered off and (2) with said 2nd language if said 2nd language mode was manually selected by the user before said communication device was powered off.
