have a look in cydia for "sos iphone cydia" install that repo then when it refreshes have a search for "mobilemusicplayer flip" install that and your music and video will be combined into the iPod.app.
I had to respring after exiting cydia to get the iPod icon to show.
side note: when you respring the iPod icon might go missing, check the very last page of apps and it should be there
