On my old 3G, my screen is full of what appears to be dust. Most likely the result of always being in my pocket. The screen was replaced since it was defective.
Is there cause for concern on my IP4 or is everything sealed?
My iPhone 4 had a small patch of dust in the top right corner of the screen. I'd assume it was there during manufacturing. Took it to apple and they swapped out a new phone for me. Took a look at my new phone and this one has dust under the screen and under the glass where the front camera is. So half to go back again. My old 3G after almost 2 years still has no dust under the screen.
