Would it be possible to create your own phone and have it be fully using libre Hard&Software?

please explain how your going to get a 3g data modem and make phone calls with it via tty faggot.

Were you born stupid?

this has nothing to do with cellular connections.

Go to H-Node
Select 3G modems
Pick your poison

Alternatively you could use a 4G modem that acts as a router with web interface, so it doesn't affect your system's freedom at all.

If you want to make calls, please remember that all cellular calls may be and are: intercepted, recorded, modified, spoofed. Using old telephony is highly anticipated by our community. Find a good SIP gateway that will act as your phone carrier instead.

They are all owned by intelligence agents or kikes. There is no good one, not one. Tox or nothing for security. Analogue on lines you layed down yourself or nothing.

nope

...

Fuck yeah!
I'll start making the logo right away!

not them but replicant is the closest thing to non-botnet you'll get out of the box

Yes it is possible.
Go to china, pick a smartphone or modem of your liking and snuck the firmware source code, and schematics illegaly (like how iphone release gets leaked and they print the phone casing earlier than date of release) or lurk a lot although it's gonna be a very long ride.
Bunnie did the same thing cracking microSD cards. Chinese websites dropped all the info he needed.
Not sure but fully libre phones might already exist somewhere in China but only for own personal use.
There's blackphone though (unless they've been ), I even remember /biz/ user back in the old days writing a non-backdoored android phone designed for black market.
It's probably blackphone but that's my two cents.

Cons:
you'll have to reimplement the whole cellular infrastructure to make it actually FOSH/FOSS
FCC
"muh terrorism/surveillance" - terrorists in office
imminent jammers/interceptors/M0ssad-NSA
there's a possibility you'll find out about some top secret "mind controlling-tier" secret patents in cellular modems that instantly makes you a vHVT

Openbts github.com/RangeNetworks/dev +
Some Open source hardware SBC / open architecture +
research about the cracking of SIM few defcons ago
= There you go. The rest is easy

Alright, guess the odds of this actually being doable is really rather slim then... Thanks for the help
