The new 2.3 update wasn't supposed to add any features, but apparently it did. metheweirdo over at Zune Boards noticed this and brought it to their attention. Pretty cool. I like this feature since I download podcasts to try out all the time. Often times I listen and realize that the podcast sucks. I have to rely on my brain to get home and remember to delete it. Now I am golden.

Now you can unsubscribe from a podcast you no longer want directly from the device - another cool feature iPods don't have! Simply click the center of the middle button while listening to any podcast to see this option!
