You know how the iPhone tracks when you've listened to a podcast? Well, mine doesn't do it right.
It says that I have listened to a podcast just after I listened to it, but after a while if I go back into the iPod part of the iPhone it's listed as brand new again! This is especially annoying for podcasts like Tech5 where I may listen to 20 a day!
By the way, I have no apps installed that I know of that would interfere with the iPod; I had a Last.FM scrobbler but I uninstalled it to see if it was the cause-which it wasn't.
