ShakeItPhoto has been updated to version 2.0 and includes an option for a new Polaroid-ish frame. You can choose either one you want in the preferences. The app crashed on me once so far, so it might need a bit of tweaking – or maybe I should restart my iPhone. There is a tiny vertical shift between using the classic frame and the new frame which is easiest to see by slightly cutting off the bird at the bottom of the photo.
