Cs are just California versions of the J, K, L, N and S. J is 82, K is 83, L is 84, N is 85 and S is 86.
You might want to do 30 seconds of research before you babble like an idiot any further. Verizon is using the same LTE 4G technology that AT&T will. And CDMA vs GSM has nothing to do with iphone being AT&T. It's just a business decision based on the amount of subsidy AT&T shells out for the...
