Despite Zuneinsider saying that there weren't any new features in the 2.3 version of the firmware, I just found one. The firmware update is supposed to help with battery life, and it has. But there is one feature that isn't being talked about. When playing a podcast, if you hit the center button, you are presented with the description of the podcast. On that screen, there is an option to unsubscribe now. That wasn't there before. Now, if they could add a "Mark as played" option to that screen, as I suggested in a previous post, I'll be happy.
