This is in the wrong forum - please move it to 'Jolla The Other Half' as it's related to hardware.
EDIT: To the topic - it looks interesting, but makes me bit worried as it lacks any hardware connection and relies on NFC+WiFi only. I hope Jolla doesn't go that way.
as the rumor clearly states, this would be an Android device / App
thus Sony is likely to provide an Apps to drive that, for Android, obviously
most likely, the specs of the device would remain "trade secret" and the driver proprietary anyway (do i need say more???)
so unless Jolla goes Android...
EDIT: as a matter of fact, Sony is more likely (if the whole thing ever passes rumour state... ) to provide a WP driver
thus NOKIA would benefit from it more or less free of charge
It would be interesting to get some attachable lens extension for smartphones camera.
P.S. Dream on, Jolla will never get that technology (20.2Mpx), you will have to choose between a cheap open-source phone affordable for all "hackers" or a "iphone competitor" for the price.
