Can't calibrate keyboard on HTC Desire

[T-money]

Hey guys, I bought my HTC Desire a few weeks ago in Korea and I have trouble with the keyboard detecting my touch properly. I tried to go calibrate the damn thing but when I go into Settings<language and keyboard the only options available are Select Local which leads to either Korean or English language and DioPen IME which leads to a bunch of options but none of which are keyboard calibrate. Is there anyway for me to calibrate the keyboard? I've tried downloading different keyboards from the market to see if they work better but when I select them in the language and keyboard folder they still don't work so I don't know what to do. Someone please help
