It's all there, but should show up in the keyboard... – Emoji Emoticon Keyboard Review

The Emoji application is awesome, and even has some extra features which the iPhone Emoji's are lacking. However the fact that it is not integrated into the keyboard which would normally show up with something like Facebook, is a shortfall. Having to do a cut-and-paste from this app into another is a bit of a challenge sometimes - it should be integrated, like emojis are on the iPhone - just sayin'. If it showed up as it does, and was ALSO integrated into the standard keyboard, it would be perfect solution.
