im on sero, they are wise to it if you try to get an upgrade before your eligible for a new contract.

I advise against calling retentions if your on sero you may lose your plan.

even paying full price on a sero plan its still cheaper for the year to just buy the phone outright.

though if many people call to threaten cancelation sprint may indeed have to price match to verizons prices to stay competitive... who knows
