- Buy http://go.tagjag.com/emoji in iTunes (.99c)
- Install and click through any story in the app.
- Go navigate through the iPhone’s Settings: General | International | Keyboards | Japanese | toggle Emoji to on
- SMS emoji graphics to anyone else who uses an iPhone – just click the globe symbol that should now appear in the SMS keyboard!
There’s also a way to do this for free (but in my estimation, it’s easier to just spend .99c on the app that’ll do it for you automatically). This should get the emoticons on your iPhone SMS messages.
