How to unlock your smily face in iPhone

Wonder why there isn't any smiley face icons in your iPhone? Actually there is!



Don't know why iPhone in US lock the smiley face input (a.k.a. Emoji, in Japan); if you follow the instruction in this post, you'll easily get your smiley face icons!



But remember, these icons are only supported by iPhone, which means if you send a text message using smiley faces(Emoji) to someone's blackberry, it won't work! They only see a bunch of weird symbols.
