I can't take this crap any more. There are three small, but very, very annoying scratches on my DSi touchscreen and I have decided to the replace it. Last time I took apart a DS was when I wanted to switch the case for my DS lite, I managed to mess up the top screen ribbon cable (a couple of tiny dents) and it was rendered useless (didn't lose much as the ds was pretty much dead before I tried the shell replacement). I have found what seems to be an OEM DSi touchscreen but before I even attempt this I would like to know how large is the risk that my DSi would be rendered useless? There are also some dust stuff I need to remove under the screen border. I have no intention of touching the top screen.
