I have been using a Japanese GF-1 that one of my friends wants to sell me. I am in the US and would like to know if I can flash the firmware with an update I download in the US. From the Panasonic web site, it is not clear whether or not there is one update for all cameras regardless of geographic location.Will it matter whether or not the menus are set to English or Japanese? Thanks.--pschatz100It's not how many pixels you have... but how you use them.
