I have read of a few posters requesting info on the FT3 innerds. My unit is two weeks old, and unfortunately the charger broke after the first week (diodes burned up). I used an aftermarket 5v 2000ma DC charger and ended up frying it. So now I have the latest Frytouch. I opened it up quite easily by removing the (4) screw covers along the top/bottom edges. Remove the stylus and insert a small screwdriver to begin separating the panels. Pic 1: Underside of main board - the two batteries are labeled 8000 MaH Pic 2: Underside of main board Pic3; Close up of underside - showing 4gb microSD card, and Infotmic x220 I took out the 4 Gb internal memory card and took a screen shot of the base data: As far as upgrading goes. I think its plausible to use a 16gb microSD card here. Not sure if the bios supports it tho. Hope this helps someone.
