As other people have said, GPS isn't necessary for cell phone tracking; it can also be used in tracking but the tracking works well by triangulation. The tracking of Malte Spitz https://www.ted.com/speakers/malte_spitz.html http://www.zeit.de/digital/datenschutz/2011-03/data-protection-malte-spitz used this process. I'm curious whether people in some countries have had success using wifi-only phones, including to make and receive calls by VoIP. There are ways that wifi can be more private in some ways in some situations compared to the GSM network, but it's also much, much less ubiquitous. -- Seth Schoen <sch...@eff.org> Senior Staff Technologist https://www.eff.org/ Electronic Frontier Foundation https://www.eff.org/join 815 Eddy Street, San Francisco, CA 94109 +1 415 436 9333 x107 -- Too many emails?
