I'm trying to remove some artists from the iPod, but it's not working. I can remove in the iTunes, and sync, but when I look in the iPod, they are still there.
The iTunes show more "empty space" in the graph, but in the iPod there's almost no free space.
I've tried to remove all mp3 and synchronize, but after the process I look in the iPod and the mp3 are still there.
Is there a way to remove the mp3 without need to format the iPod?
(I don't want to loose some applications saved data, and I'm not sure if iTunes would correctly bkp my saved games achievements, for example)
