Is there is some sort of timeout after which it gives up, or a reliable upper bound on the time it takes for a network search, and if so, do you know how long either of those two periods are?
I presume that if you ring a phone, a search is initiated, which would result either the phone being located or the phone being marked as unavailable, and that once the latter had happened you wouldn't get the ringing tone until the phone re-registered on the network.
I only ask because, from memory, the reports that I saw seemed to suggest that people got ringing tones for quite a while, and a cursory search just now indicates phones are still ringing days after the disappearance.
If that was so (unverified assumption), wouldn't that suggest that the network search hadn't yet failed to locate those phones, and that after some period of time that amounts to pretty good evidence that the phones were still connected?
After some link following to [0] I saw tweet [1], which suggests that the phones wouldn't have been on the network at all. It doesn't really answer my questions, but I think it rules out the phones as a source of information.
That tweet implies that the first order answer to my question 'how long before a search times out' is 'a long time'.
