"...how are the firmware updates obtained and applied as available?...."
It's semi-automatic. I mean, you have to start up the download manually, the rest is automatic as long you have a working
wireless connection. Did you connected the iPronto already with the wireless lan? If so, goto: [Link: pronto.philips.com]
"...Also where can additional CCF's be found?..."
You need ICF files for the iPronto. You can find them here at RemoteCentral: [Link: remotecentral.com]
"...and are there instructions in the manual on how to load..."
First you download these files to your PC and open them with "iPronto edit". From there you can download your new ICF to the iPronto
through the wireless lan connection.
