I want to get a black 16gb iphone 4 so I went into my local AT&T store this morning to see if any reservations weren't picked up. I asked if they had any, and the lady said no but that they had 32gb in black and white. I was confused as I thought the white wasn't available for a while. But she confirmed they had both colors. Do all the AT&T stores have white too, or is this just a random thing?
