Has anyone had a problem with their replacement nano?

Question

My replacement nano came with a letter saying that it was covered by a 90 day warranty. Yesterday when I thought I had a problem with it I submitted a request for support and included a scan of the letter. I just got a reply saying that my warranty is from the original date of purchase and thus expired.
Fortunately I have resolved my problem in the mean time but what happens if I get a problem that I can't fix. It appears that the so-called warranty on the replacement units is completely worthless.

Answer 1

I hope you are correct if I need the warranty! This is how Applecare replied to me:
Thank you for sending the proof of purchase.
Apple has reviewed your proof of purchase and your request to update the purchase date in our records. Your request was carefully considered. We regret to inform you that your request has been denied.
Your request was denied because the date of purchase for your replacement IPOD NANO is the same as the date of purchase of the original IPOD NANO. The replacement IPOD NANO is entitled to the remaining warranty coverage from the original IPOD NANO.
Your IPOD NANO has the following date of purchase in our records: 02/14/2006
Sincerely,
AppleCare Agreement Administration
This is what they wrote after looking at my letter about the 90 day warranty - hence my concern that it is worthless. Hopefully I never have to call AppleCare - they seem quite unhelpful.
