I appreciate the response. I will go ahead and try the linux install using the recommended files.

Regarding US standards: it's frustrating that Jolla does not put in more (i.e., any) effort in the North American market. But I can't say I blame them with our different telecommunications standards and requirements. The carrier-centric model of phone purchasing in the USA (Americans are used to buying their phones subsidized in conjunction with a phone service contract) makes it difficult for phones to make headway in this market without carrier partnership. Sadly, it is what it is.
