Behold! SMS texting & emoji with KeitaiText c:
And yes, it's also compatible with the Apple iPhone, at least in one direction, i.e. the iPhone can display all the emoji you send to it but you might not see icons for all the emoji coming from an iPhone. With custom emoji sets this issue can be solved entirely. I will try to release some of them and a tutorial in the near future.
As usual you can grab it from the Android Market. I will upload a QR code soon.
