Ask HN: 'If found, please return' on phone lock screen?

I put a label with my sister's phone # on the back on my phone, she put mine on hers. I didn't want to rely on the phone functioning in case the battery was dead.

No, but I can easily add this info to the lock screen of my iPhone in case I loose it by logging into to iCloud website.

And if it gets stolen, the villain knows where you live and can rob your house too…

ref to a friend not for himself to do not know owner identity because it increase prise of the phone
