So now that I have discoverd that the one 3rd edition has no SD slot for expanding memory after I ordered online and not reading up on it first. Although it was a good deal for what it is, from what i understand it has no SD card inside rather a memory chip, ok so let's say We locate that chip and replace it with a 2 or even 4GB chip I have no problems with the soldering part of it due to the intense soldering we do at work Mil spec microscope soldering. only thing would be to locate it and search for a compatible mem chip. if anyone has any photos, schematics this would help. any thoughts or ideas please feel free to add them here.
