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'.
