An input method (or input method editor) is an operating system component or program that allows any data, such as keyboard strokes or mouse movements, to be received as input. In this way users can enter characters and symbols not found on their input devices. Using an input method is obligatory for any language that has more graphemes than there are keys on the keyboard. This tutorial aims to introduce how to install an input method on jailbroken iPhone.
