It's worth making a case with the police if your enquiries don't get you anywhere. I lost my iPhone back in 2010 and thought it was gone forever. Someone suggested going to the police, which I did, not holding out much hope they would ever find it. But surprise surprise, over a year later they called me to tell me they had found my phone. Amazing! You need the IMEI number of the phone - which should be on the box if you still have it or if not go to Preferences - Devices in iTunes. Hover over the name of the device and you'll see the info. Go to the Investigation department at Capital Police Station at Crazy Signal. They may be able to trace it.
