2. Most of the new smart phones will use gps to provide their location, and if gps isn't available (your phone can't "hear" the satellites) then your phone will use triangulation of all of the cell towers that it can "see"

Which you should disable, as it encodes the lat/long in every photo you take.

That's an option on my phone, and compared to so much other stuff, I'm not sure that's that big a deal.
