I've been using Sailfish OS since the first Jolla phone came out in EU and Canada both. It has some hurdles but if you pay for the android subsystem it works fine. There are a lot of great native apps and you get the full linux experience.

The Jolla 2 is said to be "sold out".

Apparently, they produce the phones in batches, not sure when the next one is due?

Just received mine. Sure, the interface is far, far slicker than what is available on the Librem 5, but there are already hints of "you are not really the owner of the device" (for instance default "safety" contacts in the contact app that you cannot delete, the inability to easily use "reverse tethering" (getting Internet by USB through a computer) and so on) that will make me keep the Librem 5, with all its own issues, as my daily driver for the foreseeable future.

(And the Jolla's "hardware privacy switch" feels like a bad joke: yes, the switch is hardware. What it does (if anything) is fully handled in software.)

The safety contacts issue is legislated in Europe. Removing them is breaking the law, I believe. Can be done if you really want to hack.
