Also, the Apple discussion forums are a great place to post problems. Apple employees read through and answer if they need to. The regular members usually do fine though.
The link @eponymoushipster provided. Several times I’ve had problems with one of the many ipods and itouch that reside in my home.
I typically will get a response within 24 hours, mostly less, and always great support. I am so pleased with the help Apple provides, I probably will get MAC next time out!
