Podcast player

Has there been any talk of a media player which is better for playing podcasts than the existing iPhone player ? I use the ipod function of my phone exclusively for playing podcasts, and the navigation leaves something to be desired. In particular the right arrow key which when held down fast forwards, but if you inadvertently jab it skips to the end, is a right pain particularly when driving. It would also be nice to have the speeded up audio which you get as the fast forward accelarates to be able to be selected as a mode etc. etc.
