Earlier today, on macrumors.com/iphone, I saw a new App under "new Apps" for a television guide. So, I went to the App store in iTunes and searched for "tv guide" and several Apps came up - and all cost money. BUT, in the comments section on one of the Apps, someone referred us to a free tv guide, designed specifically for the iPhone. ON YOUR IPHONE, go to iphone.television.aol.com, and you will find an EXCELLENT television guide, designed specifically for the iPhone. Just save the webpage link into your favorites or onto your Home screen.
Check out the icon that it adds to your Home Screen for you:
It didn't add an icon to my home screen.
