I was curious what options are out there as well.

Are you:
1) Needing to mount the phone to the scope
The mounting bracket is not too expensive, and the easiest of the options. You can use an old phone, as long as the camera still works. Someone will give you one if you don't have one.

2) Or do you need a camera on the scope can be set on a bench ($$)

3) Looks like ATN makes a scope with bluetooth & recording capabilities in it. ($$$) No idea about the quality
