The flash-based pop-up player on the archives won't work with Safari on ipod/iphone, but there are plenty of free browser apps that enable flash players. I use one called "Photon" that lets me listen to any of the archives on my ipod touch and t-mobile cell phone. I've worked through a good deal of the show this way, all on my mobile devices. There is a weird catch in that you have to tap the screen every 15 minutes to keep the flash stream going, but once I got used to that, it's given me hours of mobile Best Show.
