New guy here. HELP.......... Bought new DROID RAZR 4G yesterday. Phone stays in 3G mode. Does NOT switch to 4G. Verizon setup person was having trouble initiallizing phone in 4G mode. I checked Apps/Settings/Wireless&networks/Mobile networks/Network Mode is set to CDMA only. SHOULD I SWITCH IT TO CDMA/LTE TO GET IT TO RUN 4G???? I dont want to BREAK the phone on the second day.
