Oh no... The spec of death!!!!!

lmbo... dont worry about it man... Having those people at the store open it up will cause more problems than anything else and you will probably just get more dust quicker since they won't take as much care as us doing it ourselves. It's a material possession and it will have certain flaws. Turn that screen on and enjoy that phone.

If a lot of dust accumulates look up the "HTC Evo Tear-down" video/thread on Google and take it apart yourself to blow it out... The guys at the store may just rush it and do more harm than good.
