No, because you're still going to be identified by the location of the cell phone. If you never even turn the thing on anywhere near any property tied to you, then... yes, I suppose that would work. But the mobile device is the weakest link here: they're designed to prevent the end user from having administrative privileges. The carriers love to not let you change their precious spyware and monitoring tools.Rooting or jailbreaking a phone is literally exploiting a security hole in the operating system to elevate your account to administrator status, so that you can undo or override what the carriers did before they gave you the phone. It's hacking your own device -- maybe that puts into perspective how questionable the security of any mobile device really is.
