Over the years, I've found a few unlocked phones in cabs, and knowing better than to leave it to a cabbie (some do the right thing; some won't, or don't know how to), I've taken it home, opened the contacts or texts and fished around til I found an obvious friend/spouse/family member, then called them. Now, if I find a 5S (and likely all future iPhones) with Touch ID activated and immediate scan required, I'll have found a brick. Great security, but no hope of getting the phone to the owner. It seems like the time is right for an Apple designed lock screen app that gives someone who finds a locked 5S a way to return it to the owner. Something that can send an email to the owner with the finder's contact info. Or some program by which a found phone can be taken to an Apple store and the owner can pick it up. Something, anything? Are we all so paranoid now that we'd rather lose our phones entirely than have some hope of getting it back if it's lost?
