i have recently bought a 8520 curve but my phone doesnt have the korean language inside. and i've tried putting the korean alx and the cod inside but my research in motion folder doesnt have an application loader. my phone's version is a 4.6? so what should i do? downgrade my phone to a 4.5 and put the cods and alx in it or should i download the 4.5 multlanguage or the 4.5 eastasian version?
