When you make an on-the-go playlist and then sync iPhone to your computer, the playlist is saved on iPhone and in your iTunes library, then deleted from iPhone. The first is saved as “On-The-Go 1,” the second as “On-The-Go 2,” and so on. To put a playlist back on iPhone, select iPhone in the iTunes sidebar, click the Music tab, and set the playlist to sync.
Tap Playlists, tap On-The-Go, tap Edit, then do one of the following:

To delete a song from the playlist, tap
