How about you ask for half of your money back. How much did you pay? If you paid like 30 dollars then it's a good deal. If you paid like 60 dollars just ask for half of your money back because right now it's a 1gb and not a 4gb. I don't know what to think right now though, how would he change the flash chip? How is that possible? I really doubt that samsung printed the wrong serial number. Think about it, K9NB is 4gb, like yours is supposed to be. So it basicly has the right memory chip. But wait.....it's only 1gb. And I guess there's a big quoincidence, if you change the B to 8 (very similar) it will be 1gb. Yeah right.........
Or, use that program that he wants to send you that like fixes your players memory or 'properly formats' it. Then I would borrow a friends webcam, or phone, or digital camera and make a shrort video of the computer displaying 4gb, and you load your player with more than 1gb, and then you play the file thats right after 1gb.
