I recently purchased this tablet whilst I was in china (android 2.2, 800x600). Most things work great - however, I cannot seem to get to the date/time setting option. I recall checking automatic perhaps, and now it is disabled and the time is Jan/1970 and there does not seem to be a way to set it manually. Would erasing all the data and resetting it back to the factory settings help resolve this issue? or is there another way to set the date/time manually? (Apart from the time being wrong, it seems that some apps do not work properly since the date/time is off by that much). Again - I can go to settings - but the date/time option is disabled. What is the best way to reset that? thanks, Carl.
