IPhone :: Reception Antenna Can't Work

So since I have been having the reception antenna issues I thought I would make an appointment and stop in to the Apple store today. I told the guy all my issues and he said we can either replace it or give you a bumper and see if it helps. I thought it would be a good idea if I started fresh with a new phone. He went in back and came out with a box that was NOT the nice small iPhone 4 retail box.

It was plastic looking like one of those small hardware screwdriver boxes with all the little bits. He opened the box and in it was an iPhone 4 surrounded in black foam and the phone was wrapped in a little bag. My first thought was this has to be a refurbished or one someone brought back that was having a different problem. He said "How could it be refurbished? The phone just came out." I didn't believe him cause he has a odd smirk on his face when he said it.....
