Sold my 64GB Silver AT&T model on CL for $575 today. Guy talked me down from $600 since I forgot to bring the beat up old leather Apple case. Oh well, lol.
I've sold iPhones on CL in three states now (yeah, traveled a bit for school lol) and have never had issues. I always leave a number for people to text and ask questions, I always meet either at AT&T, Verizon, or Apple, depending on the device, and I always make sure to talk to the guy over the phone at least once before meeting. Maybe I am just super lucky, IDK.
Anyway, Test driving the Lumia 520 that I found at Target for $35 on clearance. WHOLE LOT OF PHONE for $35. Makes me rethink how much of what I get from an iPhone is a need versus a want!
