I recently bought an Apple TV 2 from Amazon but I am having problems with it not waking up from sleep so I need to bring it to the Apple store to get it exchanged. My questions - - Do I have to print some kind of invoice from Amazon showing when I bought the device? Do they require proof that I actually own this thing? - How easy will it be to exchange for a new one? Will the 'genius' waste my time trying to recreate the issue at the store or will they just give me a new one without asking too many questions? TIA!
