I left my iPhone at the gym in the locker room. I know exactly where it was let. It was not there an hour later (of course). And never was put into lost and found. It was a 16 gig, like new, screen protector, black. I live in a suburb of Fort Lauderdale called Weston. The next morning, an ad was put on Craigslist for a phone matching mine and in Weston. It was a 'low' price of $400. It was the only iPhone in weston for sale for the past month. I suspected it must be mine. I filed police report. Later, I arranged a meeting with the 'suspect.' It was VERY sketchy setting up the meeting at a home depot. Later, I included the police... An officer I talked to confronted the suspects (there was about 4 'salesmen' for the phone). They admitted to the cop it is not their phone, saying that it was found at a school the week before. Anyhow, the phone was obtained and shown to me. There was no SIM card. I know it's my phone. The circumstantial evidence above is too great. HOWEVER: The serial number that shows up on the phone (I'm not sure how the officer retrieved it without the sim card) comes up close to what's on my box, but 3 characters off. The IMEI number also does not match the box. Both serials start with a few 8's. The first 5 characters of both serials match. The next three, which are three letters do not match; the last three characters, also letters, DO match. Basically the matching characters between the two serials (represented with '0') compared to unmatching characters ('x') are: 00000xxx000. From what I can tell online, the IMEI number can be changed. And the serial number on the box of some iPhone boxes does not exactly match the actual phone. I can't believe that it is NOT my phone. So, is it at all possible that the phone is mine? If so, how can I show that it IS my phone? How do I find out if someone 'owns' that IMEI number in the actual phone, and whose it is. If it 'belongs' to no one or if the person that it belongs to never claimed it missing or stolen, then would that show that this phone is likely mine?
