This may be a little confusing to understand.

How do you delete that history?

Why can't I delete songs from my iPhone 4?

Okay, so I got a replacement phone a few months back and i was never able to transfer my music. I took it to an Apple store and they basically said there was nothing they could do. And that I would have to re-download all of my 500 and something songs again one by one. So I've just been without music for a while. I just started to re-download some of my music, but I couldn't just manually add songs like I used to. I have to perform a sync. I did that, and now I can't edit or delete any of the music. This is becoming extremely annoying, and it's making me not even want an iPhone anymore. I don't see anything point in taking it back to Apple because they're very unhelpful. Especially when it comes to things like this. Any help would be extremely appreciated.
