Indeed, this only works for the latest version(s) which include the easter update allowing the bunny costume which wasn't included as a swipe theme, all the other swipe themes are still selectable but because of the Snorlax theme their nose might disappear when you shoot.

Although you can change all of the themes and do much more than I did in the Snorlax tester I intend to make a full theme shortly when I finish my brothers Jailbreak
