1) Faraday cage. 2) If the thief knows or can guess your passcode, you are screwed, because they can take over your iCloud: https://www.macrumors.com/2023/04/19/apple-responds-to-iphon...

they don't have many guesses to do that, how would they know the code given almost everyone unlocks via camera?

Read the link? Apple requires you to enter the passcode every now and then, and thieves exploit when that happens in public.

Did you go buy a bunch of lottery tickets afterwards? Cops doing their job when you give them the entire breadcrumb trail is incredibly rare. I have many stories from friends and that I’ve seen online of the cops refusing to do anything even when you can guide them directly to the location of your stolen property. I’ve personally experienced their lack of competency when they refused to follow up on stalking/harassme…

TBH having a few police officers drive to the place then spend that time probably costs more than the price of the device.

Are you suggesting that police services should operate like a service for hire? It isn't clear to me if you think the victim should hire the police to investigate (and thus decide if their price is lower than re-purchasing the item) or if you think the police are only expected to investigate based on the value of the item.

In either case it doesn't sound like a sound way to operate a police department. It seems like a good way to incentivize vigilantism though.

Find My came to the rescue when my wife unknowingly dropped her phone during a pullover to take some pix. The turnout was on New Priest Grade, the best way to Yosemite from our home. Next morning, after the frenzied "Where's my phone" search petered out, we remembered Find My. No way, I thought. Rural road, many miles away, etc. Which new phone would you like, Dear? Find My immediately found it 43 miles away. My wife…

Even with all the hate Apple gets in the tech sphere, they do have a lot of very handy features in their products.

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

Third parties are allowed to use the Find My network. I have a Find My "credit card" in my wallet made by Chipolo.

No they are not. They are allowed to create devices that can be found , but I can't use my Android phone to find an AirTag.

Yes you can, there's an official Apple app to do it: https://play.google.com/store/apps/details?id=com.apple.trac...

And a 3rd party tool that does even more: https://play.google.com/store/apps/details?id=de.seemoo.at_t...

Kind of a moot point? Enforcing the law operates on a different level of desired outcome than the goods itself are worth. imagine you get your phone stolen and instead of retrieving it they bought you a new one creates a pretty perverse incentive structure!

Find my works without a network connection. So if the phone is lost without signal and another iOS device comes in range it will remember seeing it, and then upload the location to apple for the devices owner to see when it has internet again.

Oh really. Wow that's pretty amazing. I thought it worked by piggy-backing off the connection of nearby devices meaning that those nearby devices would still need to have an active network connection while near to your device. I didn't know that it would remember the location of a device and then upload that location later on.

It's like 50-100 bytes of data per device seen to cache, not exactly data cap shattering amounts :)

Timestamp + GPS coordinates + device ID is about what gets sent to the cloud for each device.

Back in the mid-90s my dad lost his car keys. Turns out they were in his dressing gown (we’re British) pocket, in the wardrobe. So he bought one of those keyrings where you whistle and it beeps. This was a Saturday and we were visiting my grandparents, his parents. He told his dad, by now with a mild case of the Alzheimers, that he’d got this thing and that “you beep and it tells you where your keys are”. Well my gra…

No wonder he was confused - how does a person beep? Surely you whistle and it beeps?

Oh, wow, I didn't realize "Find my" worked even when both devices are offline! But it makes sense – all that's really needed is GPS and Bluetooth. Were you able to access it right there without signal, or did you need to move to an area with coverage for it to sync?

Not really. The phone only appears "off" but is in-fact in a low power mode providing beacons. It won't work if the battery were removed. Also, modern iPhones use tower-assisted GNSS (GPS, GLONASS, Galileo, QZSS, BeiDou, and NavIC) so the satellite isn't necessarily Navistar. With fewer or no towers, and positioned in an odd orientation on the ground, a good fix becomes much less likely, and the range can increase fr…

Sure, how else would it work? But people usually don’t disassemble their phone before losing it on a train/in a taxi etc.

> modern iPhones use tower-assisted GNSS

Yes, but GP says they didn’t have cell coverage where they lost it, so that wouldn’t help.

Just a small note, but your contract is with the retailer - if it's not delivered, tell Apple or whoever. It is up to them to get the goods to you.

Try that with most retailers and the conversation ends at delivered. Your only option is to hit them with a summons and that's not a guarantee. So with due respect that reality doesn't exist. One reason I buy stuff from Amazon mostly is they are big enough to eat the issues and I put enough business through one service to be a customer worth keeping. Everyone else, not so much. I won't go into how shit Apple are on t…

Just do a chargeback then

If I had 2 wifi access points a meter apart would that me enough to be able to locate the device either behind or in front of the two antennas?

I assume I would need two wifi USB dongles for my PC and some sort of way to determine the time a beacon packet arrived but I don't know if the time difference is granular enough to be able to tell a difference in time between the two.

Has anyone tried something like this with wifi?
