Have you been able to get your firmware issue resolved with the iCamera2's? I had the same issue last month with 5 of these cameras and was able to change the firmware version to V3.0.01.34 instead of V3.0.02.38 which they was when they were Comcast Cameras.
I did this by using the web GUI and installing the firmware version that I needed. The hard part was finding the right firmware version file. One of the guys on here was nice enough to share it with me.
