Is anyone having problems with podcasts in iOS4? I download quite a lot of podcasts directly on to my iPhone, and I've noticed that at first they're ok, but when I come back to them the track length is suddenly blank, and when I start playing them I can't skip forwards or backwards by dragging my finger across the play-bar-thing. This has happened on all of the podcasts I've downloaded since upgrading, and I download them from various different sources, too, (I.E. they're not all made by the same people, but are all downloaded on my iPhones iTunes App.) I'm using an iPhone 3GS. Stu.
