Iirc Cresent Moon is testing a 2G compatible version due with the next update; but it's been some time since the news.
They actually sent out a new build today actually, but it has nothing to do with 2g compatibility. I won't say what it is cuz I don't think I can but I haven't heard anything about 2g compatibility.
I accidently purchesed it and got a refund because I have a second gen but it runs fine. Graphics are toned down a bit
