I had hundreds of songs in an iPod app on my iPad. When I downloaded Cloud the iPod app disappeared with all of the music. It was replaced by a music app which is empty. Can you please help me?
Try unchecking sync music in iTunes,sync the iPad, check sync music, sync iPad again.
This is what I had to do to get my pics back when I installed IOS5 on my phone. The upgrade went smoothly except for no pics.
