I have the same thing. I figured it was moisture under the clear cover on the screen. But, it's not always noticeable. I live in Minneapolis, and if I am outside and come back in, I notice it. If my phone stays indoors for a number of hours (overnight for example) it goes away until it gets cold in my pocket again.

It's really annoying, and when Sprint stores get the phone back in stock, I'll prolly take it to them for replacement.
