Yes. The Ricoh image sync app is available for free download. It's a little clunky, but does allow you to change the focus, aperture, iso, and take a shot.

From the k-1 menu, go to the page two of the spanner settings, and go into the wifi options. Make sure you turn on the wifi on your camera, then go into the communication info. On the iPhone go to settings->wifi, and look for your Pentax camera in the list. Click on that, and enter the camera password. Open image sync on your phone, then hit the little camera icon at the bottom of the app.
The camera will enter live view mode, and all the camera settings will be available in the app. Enjoy!
