That was a big source of contention, but admittedly there was plenty of skunkworks going around internally to experiment with the officially forbidden material.

I was probably one of the first people to ever possess[ß] a Nokia device running Linux. A research unit in US wrote a library to interface with the baseband modem and provided the whole thing as a single, mostly-statically linked binary that could be used for phonecall functionality. A skunkworks team in Finland wrote a bootloader for N95 to use a Linux kernel. And an ex team member helped put together the initial Debian-based userland.

I wrote the wrapper library that under the hood ran the baseband binary, exposing a sane state machine you could then rely on from "regular" userspace. And I wrote the first, really rough contact book to make/receive calls from the prototype UI. The UI was built with a very early version of libflutter, a GL-based widget library. We built our own layer on top of it.

The prototype became known as the "Flower Phone", thanks to its default background screen. A few months after the device having been showed off our team was provided with about a dozen bright orange[0] N95 devices that ran Linux, booted off of a userspace we had built, and came with our prototype UI. We used them for on-device debugging and developing the UI layer further. Making real calls with them was a core piece of functionality.

From what I understand, the phone functionality in N900 became a reality thanks to that little project.

ß: wasn't mine, it firmly remained property of Nokia. But I used it for experimentation and making real calls.

0: the colour was used to signal the devices were prototypes.
