I recently had a hardware failure on my iPhone 4s (less than a year old still under warranty). After trouble shooting with Apple support and there being no Apple stores or authorized dealers within 100 miles of my location they decided to send me a refurb and send a box to my door so I can send them my old device. My question is do I have to send in the old phone in order for them to send the refurb? Just wondering if they just issue the refurb automatically or if you have to send the old one before they will mail the new one (I'd like to keep the old one for spare parts if possible).
