what difference does it make if you "found it on the ground"? The phone still likely has a phone book in it where you could call numbers to find someone who knows the owner. I found a phone once and I simply called the last number dialed and had the phone back in the owners hand less than 20 minutes later. You could call the provider and they could contact the owner of the phone, they do have his/her address you know. Your question, quite frankly,
s me and reminds me of the sad direction our world is heading where fewer and fewer people have any common courtesy or goodwill.
