What I find strange that they still don't have specs for the dimensions and weight... That is something they have been very coy about... https://puri.sm/faq/index.html#faq-Whatarethephonespecs

review of an early phone: "The phone is chonky. I measure it at 15.6 mm thick, 150.2 mm tall, and 75.2 mm wide."

I assume that the specs will change batch to batch.

for comparison:

iPhone XS: 7.5mm x 143.6 x 70.9

iPhone XS max: 7.7mm x 157.5 x 77.4

Earlier quoted context omitted.

Arduino, Trezor, and 3D printers (I forget the name) have all been cloned. It's a real concern for companies that are trying to fund open hardware R&D by marking up the hardware. Currently I doubt there's enough demand for the Librem phone to justify cloning though.

Well Prusa, the creator of the most cloned and world most popular 3D printer design is happy about all the clones. And they occupy different spaces in the market. Clones are $250 and the Prusa is $1000. And yet business is booming. As an open hardware creator myself my hope is always that someone else better at manufacturing will clone my work so I can source from them and focus on whatever reasons I had for making t…

Also, Librem 5 schematics are GPL, so it would be sort of weird to make copying into something negative, while using the copyleft license.

Calls don't work yet it seems

The reviews said the speaker isn't wired up. I wonder if you can call with the headphone jack?

It's purely software. An update with audio routing will be out likely this week (it's in testing, and you can already get it if you compile stuff yourself).

My understanding is that the microphone (& speakers?) isn't wired directly to the modem, but needs the CPU to replay the audio to the modem so that the modem (aka, baseband) doesn't have access to the microphone audio except when it actually needs it. So, I would think that the headphone mic wouldn't work either.

(Not a criticism of purism but of how little is required to say "Open Hardware" in general). I have to say how disappointing it is what counts as open hardware. A simple schematic and some xrays? Why not the Kicad(I'm pretty sure that's what they said they used to make it) files, or maybe an openboardview [1] .brd file that would actually help for device repair and hacking on the phone at a hardware level.

As a comparison to FOSS this is the equivalent of releasing a binary and some header files.
