And to paint it black:

One possibillity still is, even if Jolla releases the image, we could end up with user flashable XX that does not contain AD due to forementioned licensing and tracebility problem to pay for all Dalviks in use by selfporters.

Thats why i strongly hope jolla will not offer the port for free because it will propably lack AD in that case (speculation alert).

Edit, to make it clearer, in my worstcase we could end up with a (limited?) number of official preflashed Xperias sold by jolla, and an image you can flash to self owned xperias but with all license problems of regular community ports.
