Consumer-Grade Cell Phone Stalking
by Sid Steward
For the past week I've been tracking my girlfriend through her mobile phone. I can see exactly where she is, at any time of day or night, within 150 yards, as long as her phone is on. It has been very interesting to find out about her day. Now I'm going to tell you how I did it.
It's shy on details, but it says enough.
