Instacast iPhone App
Instacast is not the first iPhone app dedicated to managing your podcasts, but it is the first I have ever truly liked. Its most notable feature is that it offers over-the-air updating of your podcasts. You can update all your podcasts at once, or just one subscription, or even just one episode at a time. It will update the listing of all the new shows, their descriptions, length, and more. From there you can stream the episode right away or download it for listening to when you’re not online. Instacast even remembers your spot for each episode you’re listening to and you can resume where you left off — even if you were streaming.
