From what I have read and received from verizon customer service rep. You either buy the new phone outright or over 24 payments. Send in your trade-in phone and within 2-3 billing cycles (months), you will start to receive the $27 credit to your account for the next 24 months.

I agree. If you are looking to upgrade after a year, it's not a good deal. If you are okay with having the same phone for 27 months before upgrading, then it's a good deal.
I wonder if you get then next iPhone if the credit goes away? thats what i am worried about.
