One of our local Cell Phone Experts, Ron Mapes sent me the following information:
Check out this news video. Keep your cell phone close. Interesting thing is that there would be a call detail record will be created on the mobile switch. Not totally undetectable.
I watched the video on the youtube link below and since I am not very savvy on this stuff sent Ron back a note and asked him if this really could happen. Ron said:
Good Morning Henry,
It seems that along the supply chain somewhere the spy ware gets loaded on the phone. Or if you happen to let someone use your phone they can load the spy ware. In the old days a scanner or network analyzer could be used when the signal was analog. Now that the signal is digital those boxes cannot be used. Interesting stuff. Ron
