Lost my phone here on the 19th of July. Find my iPhone showed that it was found and moved all around on the map at Six Flags. I have 3 emails from Find my iPhone that shows it was found and located there. I've called several times to retrieve my phone just to be told they haven't found it. I've filed a report with the BBB and the police department at this point. Someone on their staff had to have stolen my phone if they 'still haven't found it'.
