Hey I have recently purchased an iphone. He sold me a broken 3g 16gb he told me it just stopped working one day, the phone wont turn on at all but when you hook it up with a usb cord the screen turns white. It shows no sign of being dropped and looking in the headphone jack its white. I looked up the serial number and it is under limited warranty. My question is if I take it to the genius bar would they not replace it because the serial number isn't under my name and also does it sound like it would be covered under warranty?
