Just email support: support@athinkingape.com telling them to get IOS 6 on it. or use feedback. I'd love to use the lollipop emoji I think many people have been wanting PIMD to update so the new emoji would work.
I think they are not allowing the new emoji to be use because it require IOS 6. And since not everyone has update their apple device to IOS 6 then they cant change it. If they do change it then those who dont have IOS 6 will bot be able to play pimd. I'm not very smart about these kind of stuff so these are just my thoughts
I have a panda cover for my iPod and a panda hat and I use to have a bunch of panda pictures on my iPod lol
