CBS Interactive has released an updated version of its official iOS app which enables you to watch full episodes of your favorite shows.
Version 1.5 lets you view photos in fullscreen on the iPad, use the cast pages to follow the Twitter feeds of your favorite CBS stars, and offers the ability to add shows to My CBS. Some stability enhancements are included as well.
The CBS app is free in and of itself, but you need a subscriber in the United States to use it. Video is accessible both on WiFi and cellular wireless.
Some shows are available 24 hours after first airing, while others will become available as late as 8 days after their initial broadcast.
The CBS app is compatible with iPhone 3GS, iPhone 4, iPhone 4S, iPhone 5, iPod touch (3rd generation), iPod touch (4th generation), iPod touch (5th generation) and iPad and requires iOS 5.0 or later.
