If you connect your cell phone to the laptop, can you access the cell phone from the laptop? (Apple)
Yes you can do that too
Yes, but you need additional programs. I know airDroid on Android, so it can be used for remote access. VNC always works, even under Apple. The VNC server for Apple is called Veency.
Nope you can only access the hard drive if you allow this on the cell phone as a setting
