Are smartphones any good? (was Re: Oneplus One support)

[dimonik, dimonik]

Free dumb phone is not enough for freedom/privacy.


Lets assume freecalypso-sw reached the goal and produce this phone in the
pocket:

1. You still will be tracked by telecom network (exposed location);

2. Your voice will not be encrypted using trusted algorithm (End-to-End)
because this is dumbphone as thus will obey badly broken standard GSM A5/1
- A5/3 algos with SIM card's loosy 64bit keys;

3. Your calls/sms'es will travel across telecom network and will easily be
accessible for prepared adversary (SS7 hacking);

So your data still completely insecure, and you better not to use this
phone.



Better goal is probably dumb-smartphone at least capable to send traffic
over data-connection and able to run free OS/crypto software for end-to-end
encrypted communication.
