If you're looking for a fully functional phone i would recommend getting the Fairphone 6 with my image, it is almost fully functional and i will make it so in the coming days.
You can also purchase these trough my shop if you want, but the image is open source and free to download, so any fp6 will do.
And yes, if I do end up making the riscv phone (or any other hardware) everything will be open source, the hardware and the software.
Should I get to the point where i will be selling them ill probably sell them as both kit and fully build.
But one can just take the files and order the parts themselves and assemble for no cost.
I do have to say again that actually making this is still very much an unknown, the FP6 will be available much faster. But i can promise that if a catcrafts original phone will be brought out it will be fully open in all aspects to the maxium of my ability. (For example modem firmware is closed and signed so while i really want to open source it i myself don't even have the source)
