Anyone have experience in selling the 4S? Mine is black, without SIM lock or branding, 16GB and from october 2011. It basically looks like brand new and it comes with the original box and all accessoiries besides the earpods. Additionally I have apple sock, a case from InCase and one out of silicone. How much may I get for it? My cousin offered me 280....But keep in mind, I won't sell it before the 5S is announced.
