I have decided to go with the latest update, even if it does lock the phone down, just to see the continuing evolution of Sailfish on Jolla.

I can understand the panicked response to the "Evil Maid" exploit. however if you use a Software Defined Radio configured as a GSM mast then you could probably achieve the same exploit over the air without the need to physically access the USB port.

There is ample support for FOSS implementation of GSM on SDR as used at the Burning Man Festival
