Phones Programs/Partners - Any mileage rewards for cell phone service?

I have had it with my AT&T cell phone service. They are really the absolute worst! Poor connections, dropped calls, incredibly high rates, etc. Anyway, does anybody know if there are any mileage rewards for purchasing a Sprint phone and agreement for cellular service? If so, could you please provide a link, number, or code that I would need? Thanks.
