Some hardware speculation for change. I noticed that HTC One Mini and HTC First have quite identical looking specs (Snapdragon 400 8930AA at 1.4Ghz) as the ones for Jolla. My bet would be that will be the SOC used. Does HTC still do ODM / Designing for other companies? If they do, it might mean that the manufacturing (+some of the design?) is also done by HTC.
