No, I'm not being funny, when I look at my Curve when the screen is lit up it looks like its slightly concave. When I turn it and look at it from the side it's straight. Is it maybe a defect in the screen or does everybody's look like that? And no I'm not drinking or doing drugs.
Mines flat but then again I am drinking. Its probably your homescreen image making it look that way. Mine does look a little funny when my screen is bright.
