Regarding buying speckled green FP4:
the device has already been delivered to some people. But as the device is very new there’s still a huge backlog in delivery and the global chip shortage doesn’t make it better.So February or March 2022 sound correct.
Be aware that it’s not guaranteed that the device works perfectly in US (with different frequencies) and that you won’t get support there (one of the reasons Fairphone does not deliver the device to US yet).
