How do i view my purchase history? The links in my email do not work.

in itunes app

you will see an option on the right hand side of the bottom navigation bar that says purchases (or updates) click there.

you can also view it from itunes on your computer, log in, click on your apple id and click MY account, view purchase history.

It's different for music than it is for apps. I'll assume you're talking about music.

Open iTunes on your iPhone, go to "More" in the lower right, and click "Purchased". I'm also assuming you have iOS 6.0.1.

For apps, open the App Store on your iPhone, and then click "Updates". The "Purchased" link is there.
