If I buy the no contract unlocked iphone 6 that Apple is now offering and get a nano-sim card from verizon, will it work with my current verizon plan? I just got back from Apple store and they are saying that it will work but only on 3g and not 4G LTE. I currently have an unlimited data plane with the iphone 4s and am looking to keep my unlimited plan. Will I be able to use 4G LTE just by acitvating the unlocked device?
