From what I know, all Korean Gaoranger releases are based on North American PR Wild Force releases. The little Korean kids don't care, of course, they love it anyways, but there are quite a few differences. I don't have one, so I don't know how exactly it differs, but with the Jungle Phone (Korean), you cannot change the animal attachments because the phone doesn't come with them. The wings inside the phone are not movable either. I think if you look up the Wild Force Growl Phones, you'll get an idea of the differences.
