optic lens broke?

[sanyo]

so i bought the hero to test it out and first thing i noticed is that there is a very distinct rattle when laying down the phone. It's towards the top of the device.. i read some place that it's the optical lens within the camera. I ordered another one hoping to have it fixed, yet again, the replacement (new) was the same way.

Can anyone shed some light on this for me. I don't think it's a common issue as I did a search for rattle on this particular forum and it returned one thread that didn't answer my question.
