For those that want EMOJI icons but don't want to fork out $.99, boy do I have the cure for that. Some of you probably already know about this, but the original easter egg digits did not work on my fw 3.0 b2. However, the following digits DO WORK!
Make sure you do this now so you will have it. Once you do, back up your phone and whenever you restore from backup, you will forever have emoji.
On your phone, search for the SPELL NUMBER app. It is FREE. Put in this series of digits:
91929394.59
CLOSE THE APP - you can't hit return or anything else after you put in the digits and the app "spells" it out for ya. Go to your settings/general/international/keyboard -> under JAPANESE, you should see enable emoji toggle.
I restored my 3.0 beta 2 as a NEW iPhone because my youtube doesn't work when I use my 2.2.1 restore backup. I lost my emoji from my previous JB. Now it works again!
Give it a shot before they upgrade the spell number app!!
