My brother-in-law works at a bar. He has had an iPhone 5C there for months, so he took it and tried to find the owner's phone number so he could contact them about their phone, but iCloud didn't let him get far.
Months went by without anyone coming back to claim it. Now he has given it to me. I have tried my hardest to find at least a number to call but nothing.
Any suggestions how to get the phone unlocked or extract the owner's phone number?
