My daughter dropped her iPod Nano Gen 4 and the glass broke.
The repair went fine. The guide was extremely helpful! Thanks iFixit!
The only thing I would add is this: the glass on my daughter's iPod lifted right out when it was broken. I didn't have to slide the LCD up to get the glass out. BUT....sliding the LCD up is critical to getting the new glass in. This should be noted in the guide. There's no way to get the glass back in without sliding the LCD up. You have to slide the new glass down in the ipod, below the opening, then slide it back up to get the glass to fit in. You can't force it in if the LCD is in place - you'll break it.
