Sprint's upgrades
normal customers qualify for full rebates every 22 months
premier customers qualify for the full discount on their primary line every 12 months
if you have a new plan you most likely qualify.
I'm sure if you are late on your bills and a bad customer you probably have low value and you wont be a premier customer, other then that you should be good.
