So here's what I was thinking. As a new customer sprint offers you a 30-day satisfaction guarantee. Instead of entering into a 2 year contract why would someone not just cancel every 29 days, get full refund on expenses and then get another sprint phone? You essentially would get a month to month sprint phone. The common response woudl be you would be getting a new cell phone # each time, but if you have google voice you can alwasy use that as your phone # for all your friends and family to contact you so they will neve rknow you are changing cell phones.... Seems like a way to get a free cell phone and month to month service over and over and over again.
