Dare I ask if there has been any thought to an iOS app for the forum?
Personally, I think everything is logged somewhere by something. I don't think it is reviewed by anyone but it's out there. It's just how technology has gone and being part of this time. Who knows how far this technology tracking will go in the future.
I wouldn't worry about it too much.It's tower location, not GPS, and the phone companies collect this data too.
