If you want to, you can get the Emoji keyboard in iPhone OS 4.0 for those of you that use it. Now, to get the Emoji keyboard in iPhone OS 4.0 you will need Emoji Free! (or any other Emoji keyboard app) which is, obviously, free. To get the Emoji keyboard in iPhone OS 4.0 here’s how:

1. Start up Emoji Free! or any other Emoji keyboard app you have then exit app when prompted to do so
2. Open up the Settings application
3. Tap on the “General” option
4. Tap on the “International” option
5. Tap on the “Keyboards” option
6. Tap on “Select Add New Keyboard” option
7. Scroll down to the “Emoji” keyboard then tap on it And there you go! You now have the Emoji keyboard!

Now, this doesn’t work if you go to the Keyboard settings selection directly, and you can’t delete the Emoji keyboard as well. To do this in iPhone OS 3.1.3 (or lower I think as well) here’s how to get the Emoji keyboard:

1. Start up Emoji Free! or any other Emoji keyboard app you have then exit app when prompted to do so
2. Open up the Settings application
3. Tap on the “Keyboard” option
4. Tap on the “International Keyboards” option
5. Then scroll to the “Emoji” option and tick it to “On” And there you go! You now have the Emoji keyboard!

Congratulations you now have the Emoji keyboard enabled on iPhone OS 4.0 or iPhone OS 3.1.3!
