I was thinking that I could purchase broken activation locked/water damaged/bad esn iPhone 5s' from eBay and take them to apple and get them replaced for the OOW fee. Then o would be able to sell the phone on eBay as new(apple refurbished) and make quite a bit of profit. The main thing stopping me from doing so is I am worried that apple can tell if an esn is bad or activation lock I sensed. So can they? Any phones that I brought for repair would not be able to turn on.
