Scariest Takeaways on the Current State of Smartphone Surveillance From Edward Snowden

Several mistakes in the article.
Your phone can turn off. Removing battery is stupid.
Your phone has airplane mode. No cell connection.
It conflates the phone company and internet privacy. If google/apple/facebook track your location, GPS or cell towers will do.
If phone company records are not private, blame politicians.

The IMSI is in your SIM card, and it holds your phone number. Your phone might not be doing anything, but it is constantly shouting, “I am here. Who is closest to me? That… is a cell phone tower.”

“Your going to be bound to a particular cell phone tower, and that tower is going to make a note—a permanent record—this cell phone, with this cell phone number, at this time, was connected to me,” Snowden said.

Based on your cell phone number, government agencies are generally able to get your identity. And sadly for us, Apple and Android devices aren’t champions at protecting your privacy. Big frowny face.
