How to enable Emoji icons on your non-Japanese iPhone 3G

How to enable Emoji icons on your non-Japanese iPhone 3G. Remember the recent 'iPhone Emoji' icons with the launch of the iPhone 2.2 OS? This is good news in case you want 'emoji for iPhone' outside Japan.

An Irish iPhone developer, Steven Troughton-Smith has figured out a way to enable it on the iPhone using a simple hack. You need to edit the file /User/Library/Preferences/com.apple.Preferences.plist on the device -> whether you use a jailbreak to achieve this or merely some iTunes backup editor is up to you.

“Emoji is the Japanese name for the picture characters or emoticons used in Japanese wireless messages and web pages. Originally meaning pictograph, the word literally means e “picture” + moji “letter”. The characters are used much like emoticons elsewhere, but a wider range is provided, and the icons are standardized and built into the handsets.”
