Apple figured this in its way to promote a solid service for something that would eventually need taken care of, as it did with the iPods: the space-saving, non-tamper, integrated battery. It learned that this was a way to endorse the sleek look of its model, whether it be the iPod or the iPhone, and also have a sure money-income with the battery-replacement deal. Those that can afford to buy the iPhone and have it last, well, surely the would send it in to a trusted company that can assure a quality replacement job with guaranteed results.

That is the way business works: you identify a market, and then you target it with a quantifiable service that would be able to indugle the market.

This is what Apple learned, how to be a successful company that a fair share of consumers wouldn't mind spending extra for their services. Simple as that.
