Interesting. Although your link is 11.70$ with 50% off for me, but if you search for “find my Apple” you get many more results with lots of options around 5$

That link is less than 2usd (1.62chf) for me. I’ll never understand Ali’s pricing.

fyi: apparently that's only a welcome (e.g., first-time user) offer. As soon as I logged in, it changed the price to ~11usd per piece.

> If the SSID and password are the same, how would the phone tell the difference MAC address, but devices don't care, by design they will connect if the SSID and encryption type are the same, actually, you can create a mesh wifi network at your house with regular routers or access points by doing so, connecting them with wired ethernet.

You can, but if the AP's aren't aware of their shared clients they can't hand them off to another AP when signal strength degrades. Let's say you connect a client to AP A, then walk out of range closer to AP B. Your signal strength will suck because you're now farther away from AP A (and close to AP B). AP A won't disconnect your client to allow it to connect to B for better signal strength (that is, until AP A's sig…

While communication between APs (and forwarding of the data to clients) helps, it's not strictly needed because clients will do background scans, especially when reception is getting worse.

can you not power-off an iphone without unlocking?

Disassemble and remove the battery. I can do this in about 1-2 minutes, others more skilled can do it in <30 seconds.

While walking and without alerting the person you just bumped into to the fact that you just took their phone? More realistically, a well-prepared/tech-savvy thief could just drop the phone into a Faraday bag in their backpack/pocket, or alternatively just turn off the phone!

Fortunately, the one that my friend encountered didn't do any of that.

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…

Stolen property with an address and evidence will always get actioned. It's easy and rewarding for them. Online or telephone stuff won't. It is much more complex and requires system knowledge. It's that simple.

Is this conclusion purely theoretical, or based on any experience at all?

Because anecdotally, the cops that interacted with me and people around me where completely uninterested in doing any kind of work, no matter how easy it was.

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

Yes, but then you can push this logic to everything. Should firefighters intervene? This person dead is cheaper than alive.

Public services cannot think about making a profit, otherwise it gets dark pretty quickly.

> infrastructure Imagine if anyone, not just Apple, could build on that, creating an automatic sneakernet. Populous areas without cell towers would come online, with ultra high latency. Throughput would also need to be throttled by the owner of each device to accommodate battery consumption preferences.

We’re not that far off from the planet being covered with low bandwidth internet anyway. NB-IOT and LTE-M, along with the possibility that SpaceX can use Starlink satellites to provide low bandwidth LTE coverage, seems to give a viable path for global coverage soon Only problem is that in the short term NB-IoT/LTE-M devices are rather expensive, both upfront and monthly costs. Guess that will come down over time thou…

I never heard of those before, but maybe LoRa gateways could work as a low-cost solution if having a very low bandwith isn't an issue?

> There were enough passers-by with iOS devices that Find My worked as hoped. Wouldn't the phone tell Apple servers where it was? No need for passer-bys.

Without cell coverage?

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

This reminds me of the kind of hack I came up with, almost 20 years back. I used to work in Bangalore, and now and then, we would have a power outage in the evening that lasts for a few hours. I was single and used to live alone. I did not want to go home from the office and find myself without power. So how do I find out there is power at home? During those days, there were no IOT devices so checking them is that's…

Here in Argentina people sometimes leave inside the freezer an ice cube with a coin on top of it, so they can check if the power went off for a long while - because the coin would be lower in the cube even if it froze back.

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…

I have a couple of Tile fobs from before Apple moved into the space. They're still good enough for checked bag tracking while flying (at least to confirm the bag has made it to the terminal). Tracking is pretty limited without the subscription, but enough to sanity check. It would also work as a "last seen" location, which might be enough for your example (you don't need the network unless your device moves). Find My…

>Find My should also give you a push notification if you leave a device somewhere?

It does.
