Prepaid customers pay full retail price for their devices. They don't have "upgrades" available on their account.
I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
That makes no sense. People get subsidized upgrades because they are agreeing to a 2 year contract. You don't have contract with pre-paid so no you can't get a discounted phone for pre-paid. And if you go on postpaid you might want to re-think about taking that subsidized upgrade because you must realize you are locked into a 2 year contract and you won't get to upgrade before then. Unless you need more than 6.5 GB of data I'm not sure why you would switch from pre-paid.
