Can the iPhone 4s get dust under the screen?

So i herd that iPhone 3gs and lower has a space between the glass and the screen but the iPhone 4 and 4s the glass and screen are glued or fuzed together so is it true that you can't get dust under it. I know that it can happen when it was made but i mean how would dust get between the glass and the screen if there's no space for this to happen.

I don't think so.go to the apple store and get them to check it out

Don't you think you have asked this question in a wrong category?
