Okay. Using established terminology is always nice. :-)

The device therefore is "unlocked", i. e. I have the password and
I can interact with the apps. One important thing I have to verify
is if the device is _registered_ so installing apps via App Store
is possible. I _think_ it is, but I don't know yet.

I have seen that dialog before (when pairing the device), and I
didn't get into the "trust loop" where the dialog appears again
and again, even if you tap "trust" (as described as a problem
in some web discussion forum I took my first suggestions from).

This will be interesting to check next week.

Thanks for clarification!
