So I've gotten the body open and done some exploration. It looks like the headphone jack is blocking the spot where FFC would sit. Maybe it would be possible to put it underneath, but it doesn't look like it. This teardown was a bit more complicated than the i9000, but it is still possible.
If anyone can figure out how to get the display up, please let me know. I wasn't able to do so but would like to in order to scratch off the Verizon logo.
Forgive the picture quality. These were taken with my iPhone 3G. Without further ado...
All of the parts and pieces
Camera module
This picture shows the square spot where the camera sits, along with the headphone jack in place right below it (top of the phone is down, sorry). The round slot is where the vibrator motor sits.

Sensors not lifted, but not locked into place here
This FFC project isn't looking too good. Thoughts? Are these pictures showing up correctly?
