If you've hacked your iPhone, you can install it by downloading this and unzipping it into /Applications on the phone. If you don't know how to do all that, then get yourself AppTapp and download it quickly and painlessly right on your phone.

Note: The iPhone version harkens back to the good old days of version 1.0 and does not include the much-touted motivational messages introduced in PigShooter 2. Sorry, but we feel that if you've got an iPhone you already feel pretty good about yourself and don't need the mental pick-me-up provided by the motivational messages.
