Like Matt, I had a Jolla. Got a review unit from them on Dec 22. Used both Vodafone and Telstra, and had exceptional signal on both networks.

Telstra, will having 4G on that SIM (as shown by my Lumia 925 and BB Z30) was only showing 3G - but seeing as its Software related, we won't know if they will support it in the future. (Based on the frequencies that SHOULD be supported, I see no issue).

Manual config of access point was only needed with Vodafone SIM, where as Telstra configured fine.

Hope the post helps
