It can also be uploaded to the MSFT Office schedule.

After sync is complete, PBS opens. On the top left, select Tools and scroll to Export Schedule to Calender Application. Whole range of options, but select .ics and save to desktop.

Now you can email that file to iPhone, or if you have Office, double click to open, or open Office and select File scroll to Import and Export, highlight .ics file and you can make it its own calender or merge with your regular calender. Clear as Mud?
