The solution is easy and is what I have done for the past 4 years.  The 
use of cell phones in the lab or lecture is forbidden.  You can use them 
in hall, just not in the laboratory or the lecture hall.  The penalty 
for violation is easy, a zero for the student for that lab day.  In 
lecture, you tell the students you will deduct five points from 
"everybody" on the next exam.  As a result, the students police themselves.
