To extend this - if you have HK firmware you will get traditional characters and stroke and pinyin input (which is a little strange, since pinyin is not traditionallly used in Cantonese) - the Taiwan firmware gives you traditional characters and a choice of stroke or Zhuhin (bopomofo) input, and the China firmware has simplified characters and stroke/pinyin input.

The DB2020 HK firmware has both traditional and simplified Chinese in it - although this appears to be only for display, and the input methods are just traditional (hk).
