I’ve been under the impression that when the iPhone is launched next year in Asia, it will have Korean and Japanese input, but not Chinese. Unfortunately, I can’t locate the source that originally mentioned it. Anyway, it seems there’s already a hack that allows the ‘Sinification’ of the iPhone.
However… this only appears to change the menus. You know what I really want Apple - or someone else - to provide? I mean, come on: this is a touch-screen device. I want to be able to write characters on the screen with my fingers, and to have hanyu pinyin options. No small demand, I know, but with Chinese characters being used all over Asia, even the world, surely there’s a big enough market for someone to develop this…?
