Enabling Emoji icons on iPhone?

I have an iPhone and want to enable Emoji characters. Is there a way?

You may need an app for this. There are a few applications available at the App Store. I find Emoji Emoticons Art to be a useful one.

If you are running iOS 5 or higher, just go to Settings > General > Keyboard > Keyboards > Emoji. Now, when you're typing, click the Globe icon and you can add emojis! Have fun!
