Currently there is no iPhone version of the iCamSource software, no.
The iCamSource does support connecting to JPEG network cameras, so if you entered
http://ipaddr/getCameraJpg into the iCamSource as a JPEG URL it should connect if what Ip Camera returns is a standard JPEG image.
Actually, I just purchased Ip Camera and can confirm that it does not currently work with the iCamSource, and that is because the image that Ip Camera returns is extremely large (almost 2 MB) which is much larger than the 1 MB limit that the iCamSource expects the image to be.
I could make a change to the iCamSource to increase the max image size, but the frame rate that you are going to be seeing will be horrible, just because Ip Camera takes so long to transfer the 2 MB image file. That, and it doesn't seem to update the image at all sometimes. Ip Cameras doesn't really seem "ready for prime-time" in my opinion.
