Re: This is why.... "Listening mode only"...
At some point, a rooted phone will become a RIGHT, and the sooner people wake up and tell the carriers to sod/screw/get off, the soone we collectively might be able to pressure google and the phone manufacturers to ease up on the lock-down.
Never happen. One of the parties that want the wide-open door is the government (in the generic, not the specific). They'll always want that access as a matter of course (governmental instinct), and any attempt to get them to sign anything otherwise just results in "ink on a page". After all, who can you turn to above them to keep them in line, given that the government is sovereign and, by definition, in control of its own destiny?
And before you ask why you don't hear the same thing about Apple phones? Bet you that's because they got an insider there years ago and twisted Apple's arm, allowing them to create a more sophisticated snaffer that can't be readily detected by spectrum analysis because it only transmits sideband.
BTW, to whoever mentioned the em-shielded bag, accelerometers and gyros don't need EM to work, so if it gets a fixed via radio (which it'll get at some point because you have to use the phone), then if it's shielded it can still keep track of itself for some time while in the bag, then when you take it out again it can correct for drift before sending.
