I had Cingular for over 5 years and it has the WORST service here in Jersey.  Constant dropped calls.  I finally switched to Verizon, and it's perfect since August.  Never one dropped call.  Overall, Verizon is known for the best service, and T-moble and Cingular for all the minutes.  But what good are those minutes if you can't keep a phone call b/c it keeps getting dropped?  This is just MHO.
