New 2nd-gen nano buzzes

My brand new 8gb 2nd generation ipod nano emits a high pitched buzz. This buzz is heard at all times while the ipod is on, regardless of if the backlight is on or off. It is VERY noticeable in a quiet room, and I find it problematic!

What have other nano owners found? Do you have the buzz or not?

 

Is yours a black 8gb too?

 

I've also just noticed the weird fluctuating electrical sounds it makes when 'seeking' (e.g. if I skip ahead or back a few songs while playing). Do others have this as well?

 

I checked at the apple support discussions, and apparently others are having this problem as well. In addition, we are having a problem where the screen is blank white when you turn the ipod on by turning the hold switch off.

Anyways, if anyone else has this problem, check out:

I called Apple Support today about my problem. After explaining the problem with the high pitched buzz, the support representative told me we'd have to exchange it for a new one. He didn't ask me any further questions, or even ask if I had tried to restore the iPod.... so maybe they already know about this problem? Someone on the apple discussions (see above links) said the support rep told them it's a known problem they are investigating...
