I took my Hero in to a repair center today to have the dust cleaned out from under the screen, and also mentioned how my power button had been peeling. They replaced the power button while they were taking care of the dust issue. The back button is also peeled off a little, but it wasn't nearly as bad as the power button. Anyway, now I have a new button. The screen also looks a LOT better. They didn't get 100% of the dust, but they got all of the annoyingly obvious particles.
