I want to know, because I don't want to waste money on something that isn't compatible with my iPad. Thanks.
The iTunes descriptions says it is: http://itunes.apple.com/us/app/backstab/id440313496?mt=8 (Read the requirements) Other than that I don't know.
I have heard that it is iPad 1 compatible and I have heard that it isn't. I reckon it might be compatible, but it won't have great graphics like on the iPad 2.
