I got a replacement iPhone yesterday due to dust under the screen of my original. The new one is dustless, but has something that looks a little odd to me. 1) There is a border of the lcd that is inactive - it doesn't light up when switched on. I don't remember my original having that, or am i dreaming? 2) This border seems to be uneven. One side it is less than 1mm, the other it is 2mm. And all there is a bigger gap at the top than the bottom. See the pictures i have attached. It is most noticeable when using the iPhone in natural light. It doesn't really effect the operation of the phone, i just wondered if i have ended up with another sub-par iPhone? Cheers!
