On my new iPad, the gasket on the top, near the lock button seems to be sinking in. if you run your finger around the case you can feel the edge of the glass and the aluminum edge in that spot. The rest of the edges are smooth and tapered. It's not really noticeable to the eye unless you really look for it. Is this a problem, or normal? I'm just curious because the iPad also has a very blue tint to the bottom and a yellowish/almost pink tint toward the top that has been getting more pronounced since I got it, and I don't know if it's worth going to the genius bar. I actually kind of suspect that the screen was all more yellow or warm at first, but the bluish section is what's burning in from the bottom of the screen where the battery seems to be warmest.
