Re: Absolutely every mobile can be tracked
Err - no. There are multiple companies out there that sell solutions that locate mobiles without GPS. Granted, it's not as accurate as GPS by a fair way, and yes, turning the phone off prevents it being tracked, but it's still possible and it happens in pretty much *all* the operators that maintain the network hardware (not sure if MVNO partitioning is widespread). Primary use case is to work out if an area of a cell (that may otherwise be reporting excellent call metrics) is suffering from coverage/quality issues. It's mainly done for monitoring during call/data sessions, but it's not that hard to force the mobile to connect to the network.
