Sometimes I've been getting random messages when I try to download certain podcasts through the itunes app on my iphone that say, "Podcast can not be played on this iPhone" And it will not download or stream the podcast. My phone isn't jailbroken and all factory settings, so what is going on here? Is it just a random error in the OS or itunes store? Or did the podcaster actually upload the podcast in the wrong format? I can't imagine Apple even making it possible to upload in the wrong format though, given how controlling they are about the itunes store. Anyone know what is going on?
