Regarding the altitude of Flight 93 (for cell phone usage), and
answering my own question:

This page presents the flight recorder data for 93.  Most of the flight
was at 35,000 feet; then in 20 minutes it descended approximately
linearly from 40,000 to 5,000 feet, which was the time of the last call.
It crashed five minutes later.

However, I don't see how this page offers "Proof Flight 93 was shot
down".
