Not sure if it will help you, but I have seen people make vacuum attachements out of drinking straws. A little putty, a can lid and straw. Or whatever (half a tennis ball works well too).
Like I said, not sure it will help you. I've seen people mention this problem before, and they (and you) should just return the phone. Dust should never get under the screen.
