Emoji can be added under keyboards. No additionally apps necessary. I believe this has been available since iOS 5 without any additional apps. After its enabled you can tap the globe icon to view available emoji to paste.
Oh nice. Yeah, I originally added it under keyboards via Whatsapp. Didn't realize it was officially in as of 5.0. No app required = less apps!
