Help dust under screen, i think?

[hahaha what]

note: this is an artist rendition because my digital camera is terrible and i couldn't figure out how to get the dust in the shot. but it looks just like this

it's a black speck under the screen that can only be seen on bright surfaces and only if you are looking at the screen head on. i'm not sure if it might be a dead pixel.

i can certainly live with this problem although i'd prefer if it wasn't there.

1. is this a dead pixel or dust?
2. how do i fix this, can i just exchange it at the vzw store whenever they stop being sold out?

One sure way to get dust under the screen is to stick it into your jean pockets as this is a nesting place for pocket lint.
