i work for Verizon and i hate them
for the record, Verizon, Sprint and Alltell are CDMA
Nextel does free incoming from everyone but they suck so bad its not even worth it, plus those plans are very expensive.
The only network even close to Verizon is Cingular, and thats only in certain areas. I personaly like T Mobile if thier coverage is good in your area.
