> Given the 35,000 foot  altitude at which UAL 93 travelled until it's
nosedive,

Much of the cell phone discussion is dependent upon the altitude of the
aircraft.  What were the altitudes of 93 during its flight?  I suppose
once the transponder was off it would be hard to tell.  I had always
assumed it was around 10,000 feet, but I don't recall where I got that
impression.  Is there any data?
