Found! Thank you!
So sorry to hear that, if it is encouraging: I lost my cell phone between the Freestyle Warm Up ring and the Concession stand between 7 pm and 8 pm, just before Freestyle started. Some kind person not only found it, but figured out how to navigate my contacts, call them to tell them they found my phone, and I managed to hook up them and hour and a half later to claim my phone. I offered to buy them a drink, but the guy was working for WEG site logistics and refused to take a beer. Nice people exist! Also, try the Lost & Found, many volunteers told me people had good luck with the Lost & Found (near main grounds entrance, in a brown trailer).
There is another lost and found at the volunteer gate. Talk to main gate lost and found and see if they are consolidating stuff between the two L&Fs.
