IP: Please note a change in my cell phone number IMPORTANT

[Dave Farber <farber@cis.upenn.edu>]

Due to extraordinarily poor customer service on the part of ATT 
Wireless,  involving intentional hanging up on me, lack of any 
understanding of their services and endless failures to call as promised, I 
have decided to change my service to Verizon. My new number is

Cell: +1 (202) - 841-4533

Please note and use this number when you call me

Many thanks,

Dave
