use spell number and follow the instructions
Settings> General> International> Keyboards> Emoji (emoji is on its own)
emoji should now be in your keyboard Hope this helped
and I am running iOS 4
OK... I'm on a 3Gs phone running iOS 4 (version 4.0 8A293) in US.
I made sure the Settings was not running in background. I installed Spell Number and used it. Then followed the directions above to add the keyboard and nothing... does not work for me.
Am I missing something here???
