To install the free frames, get version 1.6.7 (or higher). Then go to the Frames Browser. I like to get there by swiping upward on the live camera view screen. Kind of a cool trick for quickly selecting live frames. Once in the Frames Browser, you will see the install button for the free frames if they have not been installed yet. Just click the "Install freeframes" button and they will download and install too your phone.
