Someone has asked a question (onDPR) about this version of firmware that supposedly allows use of non-oem batteries again. I assume it is a hacked version and a Google search came up with a non-Panasonic site listing it as a download. I'd be reluctant to try it (and will not give a link on this forum) as it seems the updates after 1.2 are minimal and do bar the non-oem batteries. My 'new' G1 is at 1.2 and there it will stay. Anyone have any background to add on this?
