Access to iPhone app content

I have 17.10 now on a stick and the first impression on my old t410 is very positive.

The nicest surprise was that Caja now allows me to access content from some of the apps on my iPhone when connected via cable. This does not happen on my 16.04.2. System.

Does anyone know if that is indeed a new feature or if this can be achieved under the LTS aswell?

Thanks.
