Without cell coverage?

Okay let’s say there wasn’t any. Why would passer-bys have coverage?

Maybe a different carrier with different coverage?

I'm also wondering if Find My will save the "find", including GPS coordinates at the time, and report it out when it has connection?

You can; the thief just didn’t get to do that because they were busy getting away in a non-conspicuous way. But even turned off, “Find my” stays active these days (although you can no longer make it ring, I believe).

That option can be disabled by turning off "Find My network" such that the phone will be off and radio silent. With it on, it will continue to beacon until the battery reaches the final BMS low voltage point.

but turning it off requires your password/PIN.

I had AirPods Max stolen from our car a few months ago. A week later they popped up on Find My a block away. I hopped on my bike and tracked to a small apartment building. Using Find My will show you a “warmer … warmer … colder” kind of UI and whenever I lifted my phone to a particular window (shades drawn) Find My would say “Nearby.” I called the police and they were genuinely excited to knock on the door. A guy ans…

I had a similar situation in Paris with an iPhone. The Police were so helpful, knew exactly what to do, and were also very excited, but ultimately the Find My location wasn’t granular enough to find the phone. In an urban environment like Paris with big apartment buildings directly adjacent to each other, I think Find My is difficult. I’d have to be lucky and catch the phone during transit from one place to another,…

There should be an app people can download and you share the location data of your lost device. Multiple devices can all home in on it increasing resolution of the location via triangulation.

Find My is great. I hid an AirTag in my bike, which got promptly stolen (as bikes tend to be in London): I had near-zero hope but police _actually_ was keen to retrieve it, it evolved into a multi-week adventure where they tried to retrieve it several times but the thief just rode away. Ended up finding it in a shady bike shop, with a fresh new coat of bright silver paint. I was skeptical when I bought the airtag, I…

I recommend removing the speaker from the airtag for this use case. Plenty of youtube videos showing you how.

I assumed it would be Bluetooth. Walking/driving around with headphones powered on waiting to pair. WiFi network mirroring is smart.

> WiFi network mirroring is smart

Thanks!

I don't usually use bluetooth _that much_ so I didn't think about it. My cousin's truck was around, which was indeed paired with the phone - but it would have been a bit more cumbersome to use in the search anyways.

Have you read up on how Find My works? I don’t see how it’s a spy network when only the device owner can see where a device is. Lots of people imagine that every Apple user, or at least Apple themselves, can track devices. But it doesn’t work that way.

The implementation seems reasonable, but how are the private keys shared between devices? It should pass through Apple some time since a phone can decrypt a laptop’s location. Or do they use bluetooth whenever near?

Generally, they have special computers that basically self-destruct when tampered with, that handle transferring key material. It's in the Apple design docs if you read them.

Apple really tries to get this right. Some countries(like China) require the computers to physically live in the country, so there could be special implementation details that alleviate some of those security guarantees, but we don't really know.

Of course, if you live in China and rely on any vendor that operates in China to protect you from the Chinese govt, you probably are wrong.

Wait until dark, shine a flashlight around and look for reflection off the glass. Or use a metal detector...

It was dark already. We did a lot of grass-searching with flashlights - but the phone was on top of the ATV, in a tough-to-spot location (by the handlebar or something, between some cables).

They have leveraged their userbase into an (admittedly very useful) spy network

Apple itself can also see where it is. This automatically means the NSA can also see where it is.
