No one on verizon with LTE has complained about being throttled, because it can't happen, at the moment.
I have had several conversations about this with techs and reps on the phone. Every time the answer is throttling only applies to unlimited 3G customers.
Verizon doesn't even have true throttling Its called network optimization and only goes into effect when you are on a congested tower after being labeled a data hog. There is no set limit to reach to be called a data hog. It's up to their discretion. Network optimization only applies to unlimited 3G customers using a 3G device. One you activate a LTE device, this no longer applies.
