As mentioned in a previous article Apple has, in this time around, added an "Emoji" keyboard to their lists of keyboard, that are in iOS 5. This emotion keyboard basically lets you put your emotions into any field with more "exactness"when you type.
To activate this useful feature here's what you need to do :
1. On the home screen click "Settings"
2. Click "General" from the sidebar on the left
3. Scroll down to the category called "Keyboard"?(duh)
4. Click "International Keyboards" from the list
5.Hit "Add New Keyboard"
6. Scroll down to the name "Emoji" from the list of keyboards ( hint they are ordered alphabetically .) ?
7. Select "Emoji" from the list.
There you go, you've added the "Emoji" keyboard. You can manage your keyboards in the same place by clicking edit in the top right corner. (Under International Keyboards)
You can now access your "Emoji" keyboard on your keyboard by clicking the world-looking button to the left of the space bar. Enjoy !
