OVERLAND PARK, Kan. -- As the opportunity to reuse or recycle idle mobile devices in the United States continues to grow, Sprint (NYSE:S) Emerging Solutions & Global Wholesale today introduced the Bring Your Own Sprint Device (BYOSD) program.BYOSD is intended to help Mobile Virtual Network Operators (MVNOs) address the growing number of inactive devices in the marketplace and offset the phone subsidy burden through the reactivation of used and inactive Sprint-branded devices on qualified MVNO price plans.In the United States alone, the U.S. Environmental Protection Agency (EPA) estimates 135 million cell phones are discarded each year. Reusing or recycling these phones could save enough energy to power more than 24,000 homes for a year. With BYOSD, MVNO customers simply bring a deactivated Sprint device to their MVNO, who must determine the device’s eligibility for the BYOSD program. Upon meeting those specifications, the device is then activated by the MVNO. Sprint Nextel Corp.
