@JanneEdelman:

THATS just what I wanted to see, many many many thanks for those great pictures.

What I was interested in was the backside pictures, and YES, there it is: Three places with "golden" contact terminals for the jolla other half to connect its i2c and NFC. Its all we need, and no doubt there will be third party hardware with qwert and other stuff in case jolla or partners doesn't come up with great hardware for this.

This is one of the main great things with the Jolla device!!!
