How difficult is it to do that? I'm a complete noob when it comes to intricate electronics repairs, I tried to take apart my DS Lite and put it in a custom shell and ended up being unable to put it all back together again After having several different screen protectors on my touchscreen, I think the factory plastic has finally bitten the dust. I don't know what it is with the XL specifically, I've never had this issue with any prior Nintendo handheld including the normal 3DS. But apparently it's not just me, and people are warning that using "wet apply" screen protectors on the bottom screen can really mess it up. At any rate, I sent my better system in to Nintendo to have them fix it for me as it's still under warranty. The one in question, however, obviously isn't as I had a NAND flash mod installed. So I have to do this myself. I assume the touch screen digitizer (or whatever it's called) itself is pretty cheap, but is it something I'd be able to do without having loads of experience?
