BestBuyCells.com gives second life to used phones from the likes of Motorola, Nokia, and Apple, refurbishing the devices for immediate use with the industry's biggest carriers. Before putting a refurbished phone back on its shelves, BestBuyCells.com's technicians test and inspect it twice to ensure the absence of defects and major cosmetic flaws. The company's inventory not only saves customers from having to sign new contracts with their carriers, it also keeps perfectly functioning devices in use so they don't pile up in landfills or become lounge chairs in a child's doll house.
