How to make N800 support Chinese display and input?

I just bought a N800, but it doesn't support Chinese. So, I think there must be some way to implement some levels of Chinese support:
1. support of Chinese website browsing
2. support of Chinese charactors input method
3. support of Chinese UI (Chinese menus of N800)

Can some one tell me some good ways to realize those or one of those functions? Some existing apps to install?pls advice, thanks alot!
