Thanks to my buddy Rich for telling me about the Chinese input for iPhone 1.1.1. Now, not only in SMS, I can input Chinese in contacts, notes, search bars… Well, anywhere that allows input. I can switch back and forth from Chinese to English. The input method is available in both simplified and traditional Chinese.
