Once my iPhone connected with PocketControl, I exited PocketControl (still running).
In iCamSource, I added a camera (named it iPhone).
Under the USB/Firewall/Built-In tab, I had a new Video/Audio Source listed as Senstic PocketCam. After setting those, started the iCamSource and all showed up.
Originally, the Senstic PocketCam source did not show up as an option. However after a computer reboot, the PocketControl completed its installation.
I never could get iCamSource to recognize a URL or IP address for my iPhone using PocketCam. So at this time, it seems limited to the wi-fi my laptop is connected to (close enough for PocketCam to connect to PocketControl).
Hope this helps somebody.
