1/10/2010 3:21:07 PM Can your phone be used to track you even if it is off?
I know that you can be tracked even if you are not making a phone call since your phone is receiving signals from cell towers even when not in use. But can it still be tracked even if the phone is off? I have heard the only way to avoid it is to take the battery out, that shutting it off is not enough.
I found this article which indicates that your phones microphone can be remotely activated to listen in on conversations in the room, even if you're not making a call, even if it is OFF....

As with most modern devices, off may not be truly off, but a deep sleep mode. In addition, phones are computers and computers can be compromised. Ever heard of jailbreaking an iphone? That's a friendly and useful way of taking advantage of a bug/s to circumvent os restrictions. What about the cellphone company's updates? I think it would be possible to hook a power down routine and turn it into a screen blank, lights off, radio off most of the time except to wake up and authenticate to the cell network then go back to sleep for a bit. I think I'll post some cool stuff to show you such a program could be installed w/o your knowledge if the attacker didn't screw up:

or do your own research - google terms: middle east blackberry failed update
There are many articles covering a failed attempt to use the trusted phone company update attack vector : >

Yes. Your phone can be tracked while you are not using it, or even when it is turned off. The only way to circumvent the system is to remove the battery. The Feds are the only ones who have the tech, but they loan it to state/local governments. For the most part, unless you are a really bad dude you don't have to worry about it. It is not very common tech.
