Hi, I bought an expensive 32GB touch from Amazon and it has a dead white pixel right in the center of the screen. I already tried to use the Apple iphone software to try to unstick it, but it did not. What should I do about this? I paid almost 500 dollars for this Ipod and I feel the screen should have all working pixels for that price. Can I get an exchange over the phone with Apple or do I have to go through Amazon? Will the next one be the same? Thanks for you help!
