The site is unavailable for me. Judging from other comments in this thread, is the gist basically to leave the phone unlocked so that the person who picks up the phone when you lose it can find out your contact information and get in touch with you?
Which isn't great advice. Sure a side effect of having it unlocked is that it makes it easier to find the owner to get in contact with. But having unlocked means it can potentially come with many downsides.
I think the better point is to make people think about how someone will get it back to you when it is locked. So either make sure you lock screen image has some contact details on it (could be as simple as screenshotting the notes app etc) or use Find My iPhone and push a message (or both!)
I can't help but think of all the things I'm auto-logged into on my phone.. Twitter, Facebook, calendar, company email, etc. And that's not even considering the tech messages and other notes that might be in there.
While an unlocked phone might be great in the honestly-lost scenario, the stolen-while-I'm-not-looking scenario makes me way more nervous.
