actually, i'm pretty sure you haven't actually *done* this: if you don't remove the five screws that secure the back to the midframe, no amount of prying will get the phone apart (unless you have a ifixit crowbar and decided that you'll want an iphone after all). note: on my phone, one of the screws was initially covered with a black sticker. it's next to where the outer-most SIM appears from under its cover.
(all this on a FP1)
"A little gentle prying with our snappy opening pick pops the clips along the midframe." - pointless without better instructions. the clips don't just "pop", it's unclear how to open the thing.
