Well I have a 3rd Generation iPod, and it's battery only lasts for about 2-3 hours. I assume i'll have to send it in and get a new battery. I wanted to buy a new iPod, but I can't do that right now. But to the point: If I send my iPod in for a new battery, what will come back? Will I have the same iPod, with a new battery? Or will I get a refurbished iPod. And if it is refurbished, will it be a 3rd generation or a 4th generation? I assume they don't have any 3rd generation iPods anymore.
