I keeping reading in these forums that there is such an incentive, anywhere from $30 to $100 for upgrading from a 3G to a 4G phone. But when I go to the Verizon stores, or call Customer Service, they say there isn't. Today was the third time I've asked, and it's getting frustrating. Am I asking wrong? I'm about to upgrade my 3G Droid X to either the Razr Maxx or the SGS3; each person I've asked said they've looked it up and don't see anything. If it doesn't exist, then fine; but I'm curious as to how some people get offered it, and others don't.
