Yep you were right. I went in to the apple store with it and they told me that is what I have to do. Still have not received the email from them though about it, and I'm moving tomorrow (although my brother is still living in the house so he will take care of it).
I got a $25 store credit. SPENDING SPREEEEEEE
You did the right thing
I would've kept it, then became guilty. Then return it
