You need to have an SMS app that supports Emoji. I personally use Go SMS which has an optional Emoji plug-in (installed separately).

I use handscent, which also supports emoji (also installed separately).
I haven't tried Go yet. I know handscnet also supports group messaging (acorss any platform i've tested so far). I think Go supports that as well, but i'm not 100% certain.
I'm not having luck keeping group sms messages sent from iphones (imessage) within a single conversation thread on either go sms or handcent? Are you?
