With Sprint it's 14 days on/off contract to return/exchange ....period. As others have said, BB is the way to go.
Speaking from experience, if you do buy it from Sprint full price, make sure they don't change your upgrade eligibility date since you didn't buy it at upgrade (discounted) price.
I posted about this on a forum some time ago and had people seriously tell me this was my own fault and that I should've waited 2 yrs to buy a new phone at discount price instead of paying full price every 6-7 mos. How I spend my money is my business. How Sprints system handles that transaction is another story and it's seriously flawed so again, make sure you check for yourself.
A Dan Hesse rep was tasked with researching my issue regarding eligibility going back several yrs. Having receipts (transaction numbers) helped greatly proving that the system was wrong and your date should not change because you opted to buy at full costs.
