Setting an MP3s as podcasts in iTunes
This issue has little to do with an iPod Nano but has to do with MP3 settings for the MP3 file itself in iTunes. To change a plain MP3 to a podcast, open up iTunes, select the MP3 then select Get Info on the MP3, select Options &amp; then look at the Media Kind list. One of the Media Kind options is Podcast so just select that and then copy the newly modified MP3 file to your iPod Nano or any iDevice. You should be good to go.
