Seems like all the benefits are only for new customers, old customers get nothing if there don’t do a trade in.
I don't know what service plan you have, but if it's one of those which just had the autopay reduced to $5/month, you're still getting your perks at reduced cost compared to new customers. The current plans have no perks at all and if you go on MyPlan, then you *have* to buy perks at additional cost, which is at least $10/perk.
