Apple is a huge supporter of same sex marriage. It could also show it's support by adding same sex couple emojis, similar to the emoji showing a straight couple with a heart to its iPhone, iPod Touch, and iPad.
Your company has been a huge supporter of the LGBT community donating money to charities that benefit the community. Upon looking through your emoji's, I noticed that there's not one for same sex couples. It would be greatly appreciated if in a future iOS update, you could include new emojis for same sex couples.
