Here's a hijack: If I bought my iPod from US and brought it here, how do I claim my warranty? I asked Machines staff and she said that must have receipt.

Lets say I haven't register yet and I register one year after using it. Will they accept?

I just asked Machines staff today at the Sunway Pyramid Branch. He confirmed that if under warranty you don't have to pay unless you don't have a receipt of purchase. He also told me that warranty covers internationally.
