My iphone won't sync to my pc the my iphone button isn't there?

Okay so. I got a new iphone and i'm trying to sync my music from my itunes to my iphone. But the button that says (iphone) next to the itunes store button is not there. How do i make that button apear. And how do i sync my music to my iphone.

ITunes isn't recognizing the new phone. That's why it doesn't show up under devices you don't 'see' it. Also depends on how you set up your new phone and hope that's correct and loaded with your Apple ID and password. Best luck.
