When going to get my Iphone replaced, what do I need to bring to the Apple store?

I got my iphone a little over two months ago and the ear speaker has stopped working properly. The phone is under my father's name, and he took it to fido to see what can be done and they said to take it to an apple store. I'm planning on going myself but since the phone isn't under my name, what do I need to bring with me?

You just need the iphone, thats all.
you can use any name.

Nothing. Just your phone. They'll look at it for you, and replace it since it's still under warranty.

Just in case bring the original recipet, father.

And definitely don't forget to bring the receipt.lol!
