This is somehow crazy! I went to
The iPhone Blog and read about Frostyplace - an App in AppStore. You install it, go through the Japanese news feed for 1 minute, close the App, re-open and go through 5 news feed again and close it.
Now to the magic!
1. Go into your iPhone "Settings" -> "General"
2. Under "Keyboards" -> "International Keyboards"
3 Chose Japanese and enable the "Emoji-symbols.
When you type something, and want use the Emoji/Emoticons - then just hit the globe on your keyboard!
Yeah - it cost 0,99$...but I ratter have this installed than something that farts, and yes you can only use it on iPhones and iTouch - but it still nice to have this option.
