the Korean input language is bundled in OS released with the mention "Multi-Language" or "All Language". You need to find one (for example from Vodafone), and install that OS on your computer.
Then use the Desktop Software toload that OS to your device. At some point you will be able to choose Korean as input language, in addition to English.
