Assuming the Jollas are made in China, then shipped to Finland, is it possible that Jolla are running their own Quality Control in Finland before shipping internationally?

Finnish customers can take faulty/bricked* devices to DNA to get replaced/reflashed, but those who purchase internationally will have to send them back. This obviously would cost both the customer and Jolla more money.

So maybe the lag is due to QA?

*Rainisto posted elsewhere that currently bricked devices have to be sent to Jolla care to be reflashed. In Finland DNA can take care of that, but international customers will have to ship theirs back to Finland
