If you want to catch up with the latest TDL podcasts on a iPhone, iPod or iPad you should try the TDL Podcast App. The app (available from iTunes) enables you to browse and listen to the the latest shows including The Media Center Show, TDL Mobile and The Custom Integrator Show.
* Streaming access to play episode from anywhere
* Always updated with the latest episodes- and an archived back catalog
* Download the episodes and play them when offline
* Playback resume (when interrupted by a call or other distraction)
* Favorites (mark the episodes you want to return back to over and over)

The app costs $1.99/ £1.19 (unfortunately the money goes to the hosting company and not TDL) but if your a dedicated listener it may be worth if for you.
