i just flashed my e71 euro AP to sg version and able to update to 110 firmware and it has chinese input now, not yet tried 200 firmware, but i read the nokia post, only europe version able to update to latest version, and they hav simplify chinese input now. But for u guys wanna input trad/simp chinese, just flash to HongKong version and they have this nokia pre-installed A4 text input software.

By the way, flash the codes, will void your warranty. And it only take second to do it.
