Hello all. I'll preface this with saying I have been an iPhone user for many years and I have no desire to keep this second iPhone. I found this phone at work. It was locked. I kept it on for 3 weeks and no one ever called. It still has service. The voice control does nothing. It is essentially useless. I brought it into Verizon and they told me they don't contact the person who originally had the iPhone, nor could they supply me with directions for how to return the phone. So here I am with a 16 gig iPhone 4 and no clear sign of what exactly do with it... Does anyone have any tips? I don't want to toss it? Can I legally sell/give it to a friend? I don't know what an ESN does or why this phone still has service but no one has tried to contact me. I essentially have a locked wifi-ready 16 gig iPod touch. I REPEAT- Verizon wouldn't take the phone and didn't have any answers. Thanks everyone.
