Well the aging depends on whether the buyer has any clue whether the next iPhone is due out in a week or so...
Which begs the question, how many people actually come to macrumors to see when the next iPhone will be released? I'm hoping maybe I can sell a week before for about $500 (4S 64GB w/ Applecare). Then buy an out of contract 64GB 5 LTE w/ Applecare..
I'm willing to do anything to get away from Verizon's garbage 3G speeds.
