AFAIK preorders started simultanously with the FP5 sold directly by Fairphone, but it was communicated from the very beginning that it will take a few more weeks to finish the /e/os port. I expect Murena will release an additional announcement once they actually start shipping devices.
Interestingly enough, I could add a phone to cart and proceed to checkout with no clear indication of the delivery time. The only indication that it is not there yet was the information on back-order availability
Yeah, it was pretty clear when they initiated the preorder phase with their announcement on August 30th, but I agree that it has become a little confusing since Fairphone itself started shipping on September 14th.
Not yet at least. The FP4 is though. All current information regarding the FP5 availability in the US can be found at: Murena Fairphone 5 availability – Murena – deGoogled phones and services. I suppose some modifications will be necessary to ensure proper compatibility with US networks. Both Fairphone and Murena are not a huge companies (when compared to other Smartphone manufacturers), so they have limited support capacity and their primary market is in Europe, so I guess it’ll take some time until necessary adaptions can be made.
