Today I seem to have lost my iphone 6 S and have a question about "find my phone". I've loaded that program in 2 of my other devices and it shows it "off line". I've attempted to call it and it immediately rolls to "message" mode what I left a brief message about returning the phone to me. I have put the phone in "lost mode" wth Notify when found. So far I haven't gone "nuclear" with Erase iPhone because that mode says it turns off the "find my phone" feature. On my boot up screen, I have a picture with 2 numbers to call if someone wanted to return it. My BIG question is if I were Erase the phone, would my boot screen message remain on when someone attempts to power it up?
