It would be great, if this could be come to life too.
working on it. slowly. one thing at a time.
btw, one of the reasons for starting a smart-ish phone with a hard kill switch on the modem is down to a story where i accidentally found out that there are over-the-air arbitrary remote code execution paths in these modems.
i had been asked by dr stallman to investigate the possibility of hard-disabling firmware updates in a 3G modem. the sales person that i spoke to *misunderstood* my enquiry, and accidentally answered the question "is it possible for governments or other third parties to arbitrarily load and run executables over-the-air without the end-user's knowledge?" with an implicit "yes".
This is part of the GSM standard. The SIMs need to be able to run Java applets insider their processor. Allowing the tracking of the device amongst other things. This has been made public in 2013:
