I recently found an iPhone at a café - looked like one of the more premium models. Tried to give it to the bar personnel, but the seat wasn't reserved and they had no clue how to contact the owner.
The phone and the case didn't have anything identifying. Tried to see if it was secured and it showed that it had a pin of six numbers. Pretty sure I couldn't get in, I tried all zeroes and 123456. Bingo. The latter one was correct
I opened the phone book just to check whether there was a favorite contact. There wasnt but there was an ICE. Texted the ICE that he phone can be picked up at the café and handed it to the personnel, solely stating that it would be picked up.
But OMG. It feels so incredibly wrong to go over those details - if I had malicious intentions I might have been able to inflict serious harm.
Please, if you want your phone to be recoverable: make sure it has some identifying info (or enable Find My) - and if you don't want that, make sure it is impossible for a hack like me to get in that easily.
Mobile phones often contain data that you don't want to share completely with one person!
