My Kindle 3 is up and running again! Thank you!

I definitely second the comment that it seems to make more sense to start prying the back off in the bottom right corner, instead of right around that delicate ribbon cable. I used an opening pick to get it started, and then used the pry tool right next to each latch point. Once I got it to the area near the delicate cable, I was able too remove it the rest of the way by hand.
