Hi guys, There is a cluster of dead pixels dead center of my iphone and I went to the local service center here. Apparently it is within spec according to them and they are not willing to help me with a replacement. Someone before me got a replacement before me because he had a phone which was apparently hanging at random intervals, the service center chap couldn't reproduce the issue but brought him a replacement and handed it over to him. I'm currently on leave from work and have to return to base in two days so can't really play the waiting game. Thanks for your time.
