I've had my evo for 4 days now, and I think I have a pretty significant amount of dust in the upper left corner. Before I call to exchange this, can anyone take and reply if it is more/less than the dust under your phone? There is also one random spec that made its way down to middle of phone (less concerned about this one...) And yes, I know there is a thread complaining about "CRAPPY" build quality, but I think this phone is stellar in all other regards. I just need some verification that I have an unusual amount of dust for a 4 day old phone. Thanks!
