Friday night I dropped my phone and it looks like there's about a 2 inch crack on the screen (not the outer glass, if that makes sense). I didn't really care, because it's still usable, and I'm sure the resale value tanked months ago with the iPhone 4 leaks. However this morning I found a horizontal line of dead pixels, about the width of an app icon. Again, not a huge deal, but I'm worried this might be progressive and end up killing the entire screen. Has anyone had dead pixel areas/cracks expand over time, or has the damage been done? Thanks!
