A:Answer 1 year parts and labor warranty covers manufacturer defects only, so don't drop it. Here is a Best Buy tip: if it is still within the return period, go back to the store with your receipt and purchase the Performance Service Plan. Theoretically you can return the phone and just rebuy it with a Service Plan right? They should be able to do a "paper return." If customer service doesn't understand, get a manager, I'm sure they would love to sell you a Service Plan.
The reason they normally wouldn't is that a person could mess up a phone and try to buy a warranty afterwards, but if you show them the phone is still good and still within the return period it should work. Your carrier usually offers some sort of extended insurance/warranty as well.
