I just got my Verizon iphone, used Greenpois0n to jailbreak it but seem to have another problem.

If I text any emoji to my friend with an iphone, she gets a bunch of weird symbols.

I then was texting a different friend, used NO emoji's, non-iphone. He also got a bunch of garbled symbols?

I am on the latest 4.2.1 firmware. Used the current Greenpoison jailbreak. On Verizon now... Anything else?

Known problem. Emoji is a non standard hack that was never supposed to be used outside of Japan.

Verzion's network doesn't properly support Emoji (at least the way it is implemented on the iPhone)

- this is not related to your jailbreak or anything you have done (except that you chose verizon)
