I have been watching on the sidelines while some friends considered them. IIUC the short version is: 1. you can't build a smartphone that's safe for paranoid people. 2. you should use physically separate devices for "LTE radio" (untrusted) and "computer" (trusted). i.e. something like getting a dumb phone and putting it into "wifi hotspot mode", except over a cable instead of wifi. Then, obviously, do all your crypto and tunnelling from the computer, so the phone is like an untrusted ADSL modem in "bridge mode". 3. purism is the best choice of integrated phone+computer device, if you're not prepared to do #2.
