I have bought the PocketTouch from the app store. There seems to be a bug with the triple tap on the status bar to change songs. You can only switch to a song that is in the list of music you were already listening to. For, example, if I am listening to a song in a playlist, i cannot switch tracks to a song in any other playlist or switch to a song by going through artists, songs, albums, etc. Anyone else have this problem?
