I have a spec of dust under my new iphone's screen and am wondering whether I should or could take it back and get it swapped out. The screen is kind of a huge deal and while it isn't in the very center (it's actually near the top and out of the way unless I am using it widescreen or watching video) it does bug me some. I guess the problem is I always feel like an ass when I complain about little things like this. I'm not being unreasonable am I?
