No. But AFAIK thy don't (and, in fact, can't) do that if the phone isn't transmitting - they don't know it is there. (Furthermore, getting that information from AT&T or Verizon is quite a bit harder than simply downloading an unencrypted file from the phone.) One of the issues with the iPhone was that (according to some folks) it keeps track of which towers it can see, even if the phone is switched off. The question I can't answer is whether turning off the phone disables all wireless capability, or just the transmitter side. I'm pretty sure that transmit is turned off - the FAA would insist on that - but a passive receiver in standby mode isn't going to require a lot of power. -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
