Hello, I've got two questions.

I recently got my 4th Generation iPod in September, and ever since
hearing about the audio defect on iPodLounge, I realize that my iPod
has this issue. I tried taking it to the local Apple store (about an
hour from where I live) and the "Genius" said that he couldn't replace
it because he didn't think there was anything wrong with it. This was
my expected reaction, considering how loud those Apple stores are,
especially in malls.

Do you recommend that I actually send the iPod in for service? I'm
not exactly sure if I want to go that route, because then it may mean
that they'll send it back and charge me for finding nothing wrong with
it at all, or they will send me a refurbished one. I didn't pay for a
refurbished iPod, I payed for a brand new one.

My second question is regarding the Click Wheel.

In the three months of using it, I've noticed that the nice smooth
feel that allowed your finger to easily glide across its surface is
now gone, and now if there is any moisture (not actual water, but if
my hands are a little more warm) I find using the Click Wheel a little
difficult at times.. The answer to this is obvious, the use causes
wear.

However, what I'm confused about is if it has anything to do with the
time when I used Brasso. I'm almost positive I didn't get any of the
liquid on the wheel, but I did put electrical tape over it so no
liquid would happen to get on it. Do you think that the tape could've
caused it's nice feel to be lost, or is it just my imagination and
this is the result of normal use?

Thank you very much for answering my questions!
