Hi, I just got my black GM1 shipped in from Hong Kong. Does anyone know where I can find the U.S. firmware to install on it? It has 50i video rather than 60i, and I assume that means it's also shooting PAL vs. NTSC. But even so I would like to be able to set it to 60i. Maybe there is some trick to change it over without reinstalling firmware? Any advice appreciated! I'll post some photos and further thoughts soon.
