Hi, because I got yesterday my new iPhone, I want to sell my old one. It's an unlocked black iPhone 4S GSM with 16GB memory. With the phone comes also a Otter iPhone case which protected the phone in the last years. Therefore it is in a very like-new condition. Besides that I have 2 charging cables for it. The installed operating system is iOS 9.0.1. I live in Palo Alto.
