I would very much recommend *against* cross-updating firmware from different regions. While I can't speak to why certain widgets may or may not be available in all regions, what I can say is that regional differences for tuners, broadcasts, and all sorts of region specific specifications (PAL vs. NTSC, 50Hz vs. 60Hz) are differences that aren't compatible as they transfer regions.
I have a 55c8000 led 3d and in my region the latest firmware is 1011. In other regions, for example the US its 1030, can i update through usb from the US website??
i heard the updates fix ghosting issues in 3d.........
and do you know if I can download skype through the PC to the TV because its not in the appstore in my region......I realy need Skype!!!!
