Just spent an hour with Verizon tech support over my Razr MAXX. Can't call out and can't receive calls. I am on an extended warranty plan that covers phone replacement. One is being shipped overnight. The Tech read a disclaimer that had to do with any changes to software or hardware voiding the warranty and full replacement costs of phone incurred as a result. I rooted once I received the JB upgrade. Does the root constitute a violation of the terms of the warranty? Thanks.
