Recently I updated my iPod touch 4th to iOS6.1.16(latest version for this device)

Even though this device is too old for using apps, it is enough to use as music and video player.

When I tried to download a new podcast from the Internet, Podcast apps was required.
So I moved to apps store, then found that podcast app requires iOS7 or later.

I used this device as podcast downloader,
it became useless!
