I'm looking to switch from Sprint PCS to either Verizon, Nextel or Cingular. I choose those 3 in that order because of coverage and customer service ratings in the New York Times "Circuits" section. I'm looking for a phone that can fully function with iSync via Bluetooth and a provider that also supports this. I've read in several places on the net that Verizon does not support bluetooth nor do they have any intention of doing so. Verizon gets the #1 coverage/customer satisfaction ranking but there is no way I'd fo with them if I have to plug in a USB cord to use iSync. Anybody use iSync and any of the above providers? What phone/s do you use? What are your overall impressions? Any advice is very appreciated.
