Apple service is one of the best I know. Thay would give you new earphones withouth complaint.
3 days ago I went to see if they could change my 3gen ipod battery, since it only lasted 3 hours. I had bought the extended warranty.
So I asked who could change the battery and the guy there told me there was no problem, that they would give me a new iPod. (A new 5gen video iPod)
I really don't know if I was the luckiest guy in the world, because if they do this with every person that goes there saying the battery isn't lasting more than 3 hours....how can Apple have profits?
Edit: I bought the iPod in BestBuy
