specks of dust under iPhone 4

After 8 months, I just discovered that there are 2 specks of dust underneath the screen.

I noticed them when I removed the film screen protector and I was under bright lights and my phone backlight was off.

I didn't see them when I first got the phone because straight from the box I put on the film screen protector.

Other than that, I don't see any other problem with my phone. The battery remains great even after I upgraded to iOS 5.

Anyways, I just wanna know if there are others whose iPhone 4 units have a dust or two under their screen? I have OCD so this kinda bothers me a little.
