just did upgrade iphone firmware to version 2.2
it comes with emoji!
emoji is a standard set of emoticons included in every japanese phone
for unknown reason, apple has locked down emoji in iphone outside japan.

to enable this wicked emoji, you need to go into cydia app
go to sections -> tweaks -> emoji
after the installation is completed go to…
phone settings -> general -> international -> keyboards -> japanese -> emoji

emoji works fine on sms and web.
unfortunately iphones that run firmware version under than 2.2 will not be able to see these emoticons.
